I have a matirx datasetA (7*7), and I want to get the inverse matrix of this datasetA and save this inverse matrix in datasetB. Could you please tell me how to implement it using sas?

How to get t-statistic with Shanken (1992) correction in the regression with sas? Thank you very much.

I want to filter and delete the columns with empty values. In the picture below, I want to keep COL129 and COL130 after filtering, and delete other columns. I am new to sas and would appreciate it if you could tell me how to program.

1. Since when I try to do rolling regression, there will be a 'sort failed' error, maybe because the amount of data is too large, 2. I want to split the dataset based on the different observations in 'characteristics', but I don't want to name the dataset using the name of the observations, I want to use dataset1, dataset2, dataset3,...

From the question above, if I want to get the datasets with name 'dataset1, dataset2, dataset3,……,dataset100', rather than naming the datasets by their observation's names. Could you please tell me how should I modify the code?

How to get residual when using SAS to do GMM? Here is an example: proc sort data;by id ;run; proc model data; endo ri; exog mp smb hml; instruments _exog_; parms b0 b1 b2 b3; ri= b0+b1*mp+b2*smb+b3*hml; fit ri/gmm kernel=(bart,1,0); by sizeport0 btmport0 ciiport0 ; ods output parameterestimates=parameterestimates; run; quit; I want to get residual in the dataset, but I do not know how to get it. Thank you in advance.
