Hi, I use PROC ARIMA to do time series analysis with intervention. I am interested in p-values for the predictors specified in crosscorr() and input() options for the procedure. I extracted estimate and standard error of predictors, then calculated the t-value. But I can't extract p-value directly. Does anybody know how to extract the p-value directly, or the degree of freedom (or central parameter, if any) for the t distribution? Any suggestion is welcome. Thanks in advance. Jean
