Sorry. I have updated the code to have include the knot selection (https://github.com/stanstrup/retpred_shiny/blob/master/retdb_admin/make_predictions_CI_tests.R). I am working on the "Good data" at the moment. - Jan. On 08...
And just then I realized the problem. nknots need to be length(knots). Otherwise knots are deleted. I am not so sure this works equally well as my original loess fit though. The fit I get with cobs is highly...
Hi, I am trying to find a way to estimate prediction intervals (PI) for a monotonic loess curve using bootstrapping. At the moment my approach is to use the boot function from the boot package to bootstrap my loess model...
