what is the most look like extention for regression in calc?

I been through a heavy statistics course and I was having bad times with Calc since that, the output report from Regression using Calc is completely different than that in MS-Excel.

is there is any plugin or Package that can help with that.

Have you looked on Menu/Data/Statistics?

yes I do, and that is what my question about, i need the output report similar to Excel with p-value (the individual coefficient) just like SAS and other statistics packages.
