A tentative solution do-file for the exercises: solution_wednesday.do


9.00 - 10.00

Introduction – the ordinary analysis and its shortcomings with a brief outlook to sensitivity analyses and an example of a simple multiple imputation based analysis.

10.00 -12.00

Understanding the missing data mechanism (MCAR, MAR and MNAR) – what can we learn from analyzing the data?

12.00 - 13.00

Lunch break

13.00 - 14.00

Our first imputation model – understanding the concept of random data, prediction and filling in missing observations

14.00 -15.00

Multiple Imputation by Chained Equations (MICE) – an iterative procedure for imputing missing values based on regression analyses (black box version)

15.00 -16.00

MICE continued – how to analyze multiply imputed data


Day 2: Wednesday, December 13, 2017
The second day will focus on how to conduct more advanced MI analyses with Stata


Slides and datasets: Missingdata_MI_II.pdf, Wooddata2.dta, Wooddata2_13.dta

9.00 - 10.00

A closer look at how Stata handles imputed datasets – the -mi-commands in Stata; MI data types; adding and extracting imputed datasets; examining missing and imputed values

10.00 - 12.00

Tailor-made regression equations with MICE – how to exploit insights about the missing data mechanism and associations between variables when imputing missing values

12.00 - 13.00

Lunch break

13.00 - 16.00

Advanced concepts in MI – passive variables, choosing a regression type for categorical imputed variables (logit, ologit, mlogit), debugging strategies when your -mi impute- will not run


Day 3: Friday December 15 2017
The third day will focus on the methodological background of the methods

9.00 - 12.00

Statistical inference – fundamental principles, likelihood, estimates, uncertainty and bias. Slides
