So far, you have not described the problem you want to address, nor the
models you think may be appropriate to the situation. Consequently,
no-one will be able to offer you much assistance.

There are a variety of ways of estimating missing values, all of which
depend on the model you have in mind for the data, and the reason(s) you
think you have for substituting estimates for the missing data.
