The National Centre for Research Methods (NCRM) is organising a course that may be of interest to the list subscribers: Course: Log-linear modelling of contingency tables Date and place: 25-26 March 2013, University of Manchester Course leader: Professor John 'Mac' McDonald Further info and registration: http://www.ncrm.ac.uk/training/show.php?article=3891 Data analysts are often interested in describing the association(s) between cross-tabulated categorical variables. Log-linear models are commonly used for modelling contingency tables, where the cell counts are treated as the response variable. A classic example is a 2-way social mobility table, where father's social class is cross-classified by son's social class, and we are interested in describing the association (interaction structure). Standard models for square tables discussed include quasi-independence, quasi-symmetry and symmetry as well as newer models which impose interpretable structures on the interactions, such as the UNIDIFF and row-column association models from sociology. For higher-dimensional tables, log-linear models can be used to study whether 2-way, 3-way or higher-way associations exist among the variables and to estimate their strength of association. Course emphasis will be placed on the usefulness and interpretation of the log-linear models presented using ideas such as conditional independence and mathematical graphs which visually represent the conditional independence structure between variables. The course is suitable for those who are completely new to R, but some practice with R before the course is strongly recommended (a worksheet will be provided). Familiarity with linear regression will be assumed, but some basic knowledge of logistic regression and/or log-linear modelling is desirable as well as familiarity with the concepts of odds and odds ratios. Course fees: £60 for UK registered postgraduate students; £120 for staff at UK academic institutions, ESRC funded researchers and registered charity organisations; £440 for all other participants. All fees include event materials, lunch, morning and afternoon tea. They do not include travel and accommodation costs.
