Hello, I have a dataset that have a couple of missing values and I DO NOT want to delete the observations with the missing values. I have read about na.action in dealing with missing values but I do not know how it applies to user-specific written code.
Is there a code you can use with your dataset so that subsequent analysis will automatically detect missing values? The following are some of the things I will be doing so that you can advice me appropriately Computing OLS estimates using the matrix approach Write objective and gradient function subroutines which will now be used in the Optimx for nonlinear optimization.
