The idea came from 2024 RAM Conference, when one of the papers talked about fractional number used in reliability. So it looks like the fractional number is already supported for some of the reliability analysis tools.
However when I tried running it by using fractional number on cost column of recurrence analysis input, the recurrence analysis tool did not like it (had error).
We have been ignoring the fail denies (those failures with no faults found), but we know that there are some failures that had missing diagnostics to be able to catch them, and we would like to include those instead of just ignoring them completely.
I am running jmp version 16.
