I uploaded statistics 1.7.0 to Debian and I get build failures related to BISTs in ClassificationPartitionedModel that take forever (at least more than 150 minutes). This seems to be a random issue. See for example this build log:
https://buildd.debian.org/status/fetch.php?pkg=octave-statistics&arch=amd64&ver=1.7.0-1&stamp=1725455778&raw=0

May this be related to the use of random data in the BISTs?
