In SAS 9.3 SAS generates that in the output, review your output from proc nlin. Do you want that in a dataset rather than in the window?

 

The format is exactly as your image...

Dear sir
I first make calculations with hand for few samples than I match it with sas results, in this way I varify sas results.

I was confused by your request, because NLIN automatically gives you the 95% confidence intervals for the parameter estimates. Bootstrap gives an alternative approach. But now I think you are requesting a way to program this outside of NLIN, possibly in the same data step used for the R2 calcuation. You know that you can use an ODS output statement to get the parameter estimates and confidence intervals saved as a data file. Then you would have them for other processing. The default method for the confidence interval is

estimate +/- t.SE,

where t is the 97.5 percentile of the t distrubiton with the error degrees of freedom (with large df, t is about 2). Thus, you can check your work.

For your information, BOOTSTRAP was only added in the more recent releases of NLIN. It is not in 12.3, but it is in 13.1. So you may not have this.

What is ANOVA?

ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
