WebbI modified _parallel_build_estimators function above but instead of imputing subdataset it keeps imputing original X data. And what is "if support_sample_weight:" ? I have no weights still it gets revoked when i run the code. I get this part the if no weight is provide each sample has same weight. WebbI want to multiple impute the missing values in the data while specifically accounting for the multilevel structure in the data (i.e. clustering by country). With the code below (using the mice package), I have been able to create imputed data sets with the pmm method.
