This makes sense. Type 3 analysis seems to work with categorical / nominal X variable. So it does not give the estimate for each category under the X variable, like the MLE does, but to give one estimate for the whole X variable.  ... View more

I asked this because SAS outputs p-value for X variable in Type 3 analysis. This p-value is not the same as that in the MLE results for each individual X variable.  ... View more

Thanks so much  for the explanation. This is helpful. Regarding this statement "They are obtained from the regression coefficient estimate and the estimate of the standard error.", so is it obtained from the regression coefficients the estimate of the standard error from the maximum likelihood estimation? SAS output MLE estimates for coefficients for linear regression.  Are the p-value the same as in type 3 analysis and MLE results? I don't think so..... ... View more

Ok. But what does it mean by explaining the variability of Y variable? Similar to R square, but applies to each X variable? How is the p value obtained from the type 3 analysis? Any readings would be useful. I find SAS output something not commonly used.... ... View more

Then what's the difference between type 3 analysis and maximum likelihood estimation results given by SAS output? ... View more

I will check first before I upload the folder to the cloud storage. Thanks. ... View more

Roughly one week. But I actually saved the folder to Google Drive. So everything should not be lost I assume? I downloaded the folder from Google Drive and opened the project in SAS, then I found something was missing.  ... View more

Is there a way I can report an issue to SAS Tech Support? ... View more

Thanks for your reply. I don't think it is related to the data. I created a diagram in the SAS EM. I added several nodes in the diagram, like the data node, the filter node, and the drop node. Then the nex time I open my project in SAS EM, somtimes the diagram disappers, and sometimes some nodes, like filter node and drop node, disapper. ... View more

Looks like the error is related to this "tables f_Status*i_Status; /* f_ = from ; i_ = into */". symbol not recognized. ... View more

I followed your code, I created a SAS code and connected to the regression node. I opened code editor in the property panel and wrote the following code in Training code. proc freq data=&_test; tables f_Status*i_Status; /* f_ = from ; i_ = into */ run; But it threw run time error. The system error returned was 3000. ... View more
