[Met_help] [rt.rap.ucar.edu #81713] History for Confidence Intervals for PSTD variables

Hi,

I'm running into some issues with plotting confidence intervals in
METViewer.  I've set bootstraping replications = 1000 and I chose "boot"
for the confidence interval type.  However, I am unable to plot any
confidence intervals for PSTD_ROC_AUC - stat_bcl and stat_bcu come up as NA
in the R data.

I am able to plot confidence intervals for the Brier Score, but when I try
to add a difference curve, I am unable to plot any confidence intervals for
that.  Here is part of the Rscript error: "zero-length arrow is of
indeterminate angle and so skipped"

I'm not really sure what I am doing incorrectly.  I've attached xml files
for my Brier Score and AUC score plots which use my mv_met_bblake_prob
database.

Thanks!
Ben

Ben,
METViewer doesn't support bootstrapping and CI for PSTD statistics (
PCT line type ).
I'm working on this now and will include into the next METViewer
release.

Hi Tatiana,

Oh ok, that makes sense.  Thank you!
