Imputing and inspecting outcomes
Good job on visualizing missing data in the previous exercise! You have discovered there are some missing entries in GDP, gdp_pc
, and trade as percentage of GDP, trade
. Also, you suspect the data are MAR, and thus imputable. In this exercise, you will make use of multiple imputation from the mice
package to impute the africa
data. Then, you will draw a strip plot of gdp_pc
vs trade
to see if the imputed data do not break the relation between these variables. Let mice do the job!

Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Load mice
___
# Impute africa with mice
africa_multiimp <- ___(africa, m = ___, defaultMethod = ___, seed = 3108)
