Enlarge number of imputations by combining mids objects
This function combines two mids objects x and y into a
single mids object, with the objective of increasing the number of
imputed data sets. If the number of imputations in x and y are
m(x) and m(y), then the combined object will have
m(x)+m(y) imputations.
ibind(x, y)

A |

The two mids objects are required to
have the same underlying multiple imputation model and should
be fitted on the same data.
