Unrecognized function or variable 'fpval'.

1 view (last 30 days)
Hello
Can you please guide me on how to fix the following error:
Unrecognized function or variable 'fpval'.
Error in stepwisefit>stepcalc (line 368)
pval = fpval(fstat,df0,dfe);
Error in stepwisefit (line 150)
[B,SE,PVAL,stats] = stepcalc(allx,y,in);
Error in newrobuststepwise (line 28)
[b,se,pval1,inmodel1,stats,nextstep,history] = stepwisefit(Xdata,Ydata);
I used a stepwise function whose parameter pval is one of its outputs

fpval is a private function of Statistics and Machine Learning Toolbox and located in MATLAB_Install/toolbox/stats/stats/private/fpval.m.
which fpval -all
/MATLAB/toolbox/stats/stats/private/fpval.m % Private to stats
If you cannot find fpval.m with "which -all", you need to reinstall Statistics and Machine Learning Toolbox again.

Good news!
restoredefaultpath only resets MATLAB search path in this session. You need to do savepath to save the path for next session.
restoredefaultpath
savepath
