Analyzing missing data patterns
The first step in working with incomplete data is to gain some insights into the missingness patterns, and a good way to do it is with visualizations. You will start your analysis of the africa
data with employing the VIM
package to create two visualizations: the aggregation plot and the spine plot. They will tell you how many data are missing, in which variables and configurations, and whether we can say something about the missing data mechanism. Let's kick off with some plotting!
