New e-books have been developed through a collaboration of the UK Data ServiceNational Centre for Research Methods (NCRM) and the Centre for Multi-Level Modelling at the University of Bristol and were created using the StatJR software based on original outputs from a project funded by the British Academy.

These quantitative methods e-books and accompanying quizzes are for direct use in teaching students or for self-study at an undergraduate level. They aim to build skills in quantitative methods and statistical software and use the Living Costs and Food Survey, available from the UK Data Service.

Using SPSS, lecturers and students can use both the practical and quiz elements of each e-book topic:

  • Examining Continuous Variables in SPSS
  • Correlations in SPSS
  • Regression in SPSS
  • Multiple Regression in SPSS

Dr Vanessa Higgins, University of Manchester, said "Working together has enabled us to create this new resource to support teaching and will encourage students to learn valuable quantitative skills for the future..."

The e-books can be accessed on the UK Data Service teaching pages

24-Nov-16: Missing data: new Stat-JR functionality to support analyses of incomplete datasets

New Stat-JR functionality to support analyses of incomplete datasets.

There are now three principal Stat-JR templates available to support handling missing data in multilevel generalised linear models; these use two different approaches.
 
The first two templates use ‘multiple imputation’ which is a widely used procedure that will handle a large number of models: a 2-level (2LevelImpute; available since 2014) and a new N-level (NLevelImpute) version are now available.
 
The second (one pass) approach is a more recent generalisation with a more robust theoretical justification (see Goldstein et al, 2014 for further details); this has been implemented in the new 2LevelMissingOnePass template.
 
To use these templates, you will first need to install Stat-JR (https://www.bristol.ac.uk/cmm/software/statjr/order-statjr/), and then download the zipped file containing the templates from CMM's missing data page (https://www.bristol.ac.uk/cmm/research/missing-data/).

09-Jul-12: Dr. George Leckie awarded ESRC Future Research Leaders Grant

Dr George Leckie has been awarded an ESRC Future Research Leaders Grant. The three-year project is titled "Multilevel Modelling of the Government's New School Performance Measures, 'Floor Standards' Target and 'Narrowing the Gap' Priority".

Each year, the Government publishes school performance tables that report the achievement and progress of pupils in English secondary schools. The Government's aim is to hold schools accountable and to enable parents to make meaningful choices about where to send their children to school. The latest 2011 school performance tables introduce new school performance measures, 'floor standards' which all schools should pass, and a 'narrowing the gap' priority that all schools narrow the performance gaps between their most disadvantaged pupils and their peers. This project will critically review these high-stakes changes and will develop and apply innovative multilevel modelling statistical techniques to explore potential improvements to the way the Government measures, reports and communicates school performances.

17-May-12: Stat-JR beta release

The MLwiN development team in collaboration with programmers from the University of Southampton are pleased to announce a beta release of our new, exciting Stat-JR software system. This has been developed as part of three ESRC funded programme nodes (LEMMA II, e-STAT and LEMMA III)

At present, while the software is a beta release, we are only distributing it in a 30-day limited licence form (with the option to renew every 30 days) so that bug fixes will reach our users quickly. It is our intention at a later date to then fully release the software when, as with our MLwiN software, Stat-JR will be free to UK academics, with potentially (though not definitely) a small one-off fee for non-academics and non-UK users.

Note that currently, like MLwiN, Stat-JR is designed to run on Microsoft Windows machines.

For more details on the software, documentation and how to apply for a 30-day download of the software, please visit https://www.bristol.ac.uk/cmm/software/statjr/index.html

02-Nov-11: The Jon Rasbash Prize for Quantitative Social Science

A new award - The Jon Rasbash prize for Quantitative Social Science has been established to commemorate the contributions to quantitative social science of Jon Rasbash, who was Professor of Computational Statistics and Director of the Centre for Multilevel Modelling at the University of Bristol. Jon was principally known for his development of multilevel methodology and its software implementation and for his research on studying social relationships within families.

The £500 prize recognizes early career achievement in the development and/ or application of advanced quantitative methods in any social science discipline. Applicants should be UK residents and in the first 10 years of their research career (including periods of postgraduate study).

The prize will be awarded on the basis of a research paper published in a peer-reviewed journal in 2010 or 2011. The applicant should be the sole or lead author of the paper. Submissions by 1 December 2011. Further details >>

24-Oct-11: Module 9: Single and multilevel models for ordinal responses

In Module 6 we saw how multiple regression models for continuous responses can be generalised to handle binary responses, and in Module 7 these models were further extended for the analysis of binary data with a two-level hierarchical structure. This module considers standard (single-level) and multilevel models for ordinal categorical response variables, where the numeric codes assigned to categories imply some ordering. We begin with a description of two approaches for the analysis of single-level ordinal data:

  1. the cumulative logit model which is appropriate for variables such as Likert scale items, where respondents are asked to indicate their strength of agreement with a statement from 'strongly agree' to 'strongly disagree', and educational tests where marks are available as grades rather than percentage scores; and
  2. the continuation ratio model for ordinal responses that can be viewed as the result of a series of sequential decisions or actions (e.g. highest level of educational qualifications).

We then show how the cumulative logit model can be extended for the analysis of data with a two-level hierarchical structure. Further details >>

29-Mar-11: Research Workshop in Multilevel Modelling using MLwiN (5 - 7 September 2011)

Tutors: William Browne, Kelvyn Jones, George Leckie, Mark Lyons-Amos, Rebecca Pillinger and Fiona Steele

This workshop is designed for researchers who have some experience of multilevel modelling, but now wish to apply it to their own data.  The workshop will be limited to 12 participants, with most of the time given to analysis of participants’ own data using the MLwiN software. Participants should be prepared to present their research to the rest of the group, including results from analyses conducted during the workshop.  There may also be more formal lectures (e.g. on significance testing, or reporting results of a multilevel analysis), but their specific content will depend on participants’ needs.

Workshop objectives

This is an intensive workshop which aims to take researchers to a point where they have the skills and confidence to specify multilevel models appropriate to their research questions, to estimate models in MLwiN, and to interpret the results.  By the end of the workshop, participants should be capable of producing a publication-quality research paper using multilevel modelling.

Applications should not exceed three pages (including the one-page CV) and must be submitted to info-cmm@bristol.ac.uk by Tuesday 31 May 2011.  Applicants will be notified of the outcome mid-June 2011.

25-Feb-11: ESRC PhD studentships in Advanced Quantitative Methods- applications deadline 5pm, Monday 11th April

The Advanced Quantitative Methods (AQM) pathway of the SWDTC offers ESRC +3 postgraduate research training in advanced quantitative methods in the social sciences and health. The pathway aims to raise the level of quantitative research skills among UK social scientists, in particular in advanced methods for secondary data analysis.

South West Doctoral Training Centre, University of Bristol.

4 ESRC Studentships in Advanced Quantitative Methods in Social Sciences & Health

We are pleased to invite applications for 4 ESRC '+3' studentships on the South West Doctoral Training Centre's Advanced Quantitative Methods in Social Science & Health (AQM) pathway. The AQM pathway is based at the University of Bristol and these studentships will run from October 2011.

The AQM pathway involves PhD supervision and core training on the application of advanced quantitative methods in the social and health sciences. It is run by leading academics from the University of Bristol's Centre for Multilevel Modelling, Centre for Market & Public Organisation, the School of Geographic Sciences, and the School of Social & Community Medicine.

AQM is for social scientists who wish to develop their quantitative research skills in order to address important substantive social science questions, and in particular those questions involving secondary data analysis. AQM is equally for researchers who wish to specialise in the development of quantitative methods to address important but more generic social science questions, rather than specific applications to a substantive topic.

Applications are welcome from graduates in quantitative social science disciplines and more technical quantitative disciplines like statistics and econometrics. Applicants must have completed a Master's degree satisfying the ESRC Postgraduate Training & Development Guidelines by 30 September 2011.

The deadline for applications is 11 April 2011.

AQM is a priority area and it is expected that successful applicants will be eligible for an additional AQM stipend of £3,000. Thus the total annual maintenance stipend for 2011/12 will be in excess of £16,590.

For more details about AQM studentships and the applications procedure, visit our website at
