confidence interval is sensitve to 'DerivStep' or 'fdiffstep' in nlpredci
While using nlpredci, I find that the confidence interval is sensitive to the 'fdiffstep' which is the step used in numerical finite difference in 'getjacobian' routine. How to fix the problem? I find that the fdiffstep is calculated using options.DerivStep in statset fucntion in statistics toolbox. How to find out the... 17 May 2010 10:12
