Hi,

Is there a way to update the parameter value in .sas7bitm file.

Suppose, I have a this file with a parameter labour as 0.8 . How can i update it to 0.81 ?

Thanks,
Deepak

I assume that this is a SAS itemstore that was created by using the STORE statement in some SAS procedure. An itemstore is a binary format that is not editable because the parameters come from the training data. 

If you know how the file was generated, there might be an alternative. For example, some SAS procedures support a CODE statement which writes DATA step code. Other procedures write parameter estimates to a SAS data set (which could be edited) and are intended to be read by PROC SCORE. For details, see "Techniques for scoring a regression model in SAS."
