mids objectsThis 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)An S3 object of class mids
A mids object.
A mids object.
Karin Groothuis-Oudshoorn, Stef van Buuren
The two mids objects are required to
have the same underlying multiple imputation model and should
be fitted on the same data.
