Hello to Sas community,
I would like help to get into table - like outest table - the confidence interval and standard error for the variables from proc nlin. How do you do?
I have statement like this so I am get parameter for every by variable patient. I will get the estimate for a,...,f out in parameters_out but the confidence limits I do not get. I see PROC REG has some TABLEOUT - is similar in PROC NLIN? I cannot find.
Help would be really good thank you!
proc nlin data = datafull_2016_2022 plots = fit maxiter = 200 save outest = parameters_final; by prtcpt; parameters a=-10 / pdata=parameters_init; model y = a*exp(x/b) + c*exp(x/d) + e*x + f; run;
I think you want the OUTPUT statement to get the confidence limits. The OUTEST is different than overall parameters.
Output out=yourdatasetname <options>=<variablenames>;
I don't suggest a specific syntax because you do not indicate whether you want confidence limits of predicted values L95 and U95, LCL and UCL or of the mean L95M / U95M and LCLM/ UCLM.
Similarly there are multiple standard error options: STDI (individual predicted value) STDP (mean predicted value) STDR (standard error of residuals)
The out= dataset name would have to be different than the OUTEST name. If you want both sets of values in one dataset then you need to combine the two sets.
