NEW: Missing Data Short Course: 27 – 29 June 2018

Registration is open for our annual short course, which will equip you to use multiple imputation (including the latest multilevel imputation approaches) to tackle missing data issues in your research. Full details here.

From time to time people have concerns about computational issues with multiple imputation; these mi_comp_issues may help.

We are grateful to (in time order)  ESRC Research Methods Programme, the ESRC Researcher Development Initiative, ESRC Research Fellowship RES-063-27-0257, ESRC Follow-On Funding scheme (grant RES-189-25-0103), MRC grant G0900724 and MRC fellowship MR/K02180X/1 for supporting the development and maintenance of this site.

We hope you find the site useful, and welcome your feedback.
