Research areas and environment

Research environment

The department has a rich and varied research environment and the Social Statistics group has close links to other departments, including Methodology| and Social Policy|. There are regular social statistics meetings and seminars, as well as workshops and conferences.

Research areas for PhD research

Latent variable models and structural equation models for categorical data

Areas for methodological research include treatment of missing values and drop out; modern estimation methods and testing under complex sample designs; longitudinal data; multi-group data analysis; measurement equivalence; survival analysis; distributional assumptions of latent and observed variables; sensitivity of the model to other model assumptions.

Potential areas of applications

  • Analysis of attitudinal and behavioural data from social surveys such as the British social attitudes, European social survey,  Eurobarometer, etc. For examples of applications and methods in the analysis of such data, please see the pages of the LCAT research project hosted by the department

Data sources

The above research questions can be investigated using longitudinal data from panel studies and birth cohort studies.  Examples of panel studies include the UK Household Longitudinal Study (Understanding Society), English Longitudinal Study of Ageing (ELSA), Survey of Health, Ageing and Retirement in Europe (SHARE), and British birth cohort studies (1970, 1958, 2000).  Further details of these and other datasets can be found at the UK Data Archive.
