[LLVMdev] [LNT] Question about results reliability in LNT infrustructure
Hi all,
When we compare two testings, each of which is run with three samples, how would LNT show whether the comparison is reliable or not?
I have seen that the function get_value_status in reporting/analysis.py uses a very simple algorithm to infer data status. For example, if abs(self.delta) <= (self.stddev * confidence_interval), then the data status is set as UNCHANGED. However, it is obviously not enough. For example, assuming both self.delta (e.g. 60%) and self.stddev (e....
