Hi, I have a few questions regarding bootstrap: 1) Is the Phoenix bootstrap method parametric, or non-parametric? 2) My understanding is that a return code of 1 to 3 is an indicator of the successful convergence. Is this true for bootstrap runs? 3) Is there a way to find out how many of the bootstrap runs have a successful covariance step? Thank you! Dora
1.Since the NLME resampling from the origin data with replacement but not from the fitted parameters, i think it’s a non parametric bootstrap. 2.I think it’s Yes. 3.it seems that use the descriptive stat module could do that or use the split worksheet module. Correct me if i’m wrong!
Hi Coco, Thanks for your answer. A successful covariance step should result in SEs for each individual run. I couldn’t find thes anywhere. I assume this is because the whole purpose of bootstrap is to obtain the SE nonparametrically. However, I was just curious if is there a way to retrieve those. Dora
