In statistical software like MINITAB and SAS, the default alpha value (critical p-value) is set as 0.15. I would like to know (1) if there is any statistic basis to set it as 0.15 and (2) if this is a common accepted value in statistics.

I have found that in this questionthis question, the critical p-value of 0.15 in R is actually based on AIC. So is AIC the basis to set 0.15 as default value?

Thanks in advance for your help!

What is the basis of setting critical p-value value in stepwise regression?
