LCSR Summer School. Day 8

Pavel Kuzmichev highlights Wednesday reports and lectures.

Pavel Kuzmichev (research assistant, LCSR) describes the 8th day of the LCSR summer school.

This day started with the practical workshops on Hermann Duelmer's course. The participants have already learned the basic theoretical aspects of multilevel structural equation modeling and started to apply their knowledge. Each participant was developing her/his own model for their research project. Everybody had a chance to get support from professor Duelmer or his assistant Kirill Zhirkov when facing some problems.

After the lunch another LCSR session dedicated to the social change and genetic diversity has started. Andrey Shcherbak (LCSR, Saint-Petersburg) presented his research on the interconnection of social development, alcohol consumption and genetic factors. Alexei Zakharov (HSE, Moscow) presented a research he is working on together with Eduard Ponarin (LCSR, Saint-Petersburg). They are trying to estimate the genetic impact of preferences for redistribution. Maxim Rudnev (ISRAS; HSE, Moscow) closed the session with his research on how the value consensus affects socioeconomic development.

In the evening Francesco Sarracino held a guest lecture on missing data. Having a lot of missing data could seriously distort the results of statistical analysis. A simple way to deal with that is to impute the mean values. However, if the distribution is non-normal this kind of imputation might make the situation even worse. A better approach was developed by Garry King. His program Amelia II executes multiple imputation using Markov chain Monte Carlo method. Today this program is considered to be the best one for dealing with missing data.
