Description
Currently the MultiIMR implementation averages mean/std dev in natural log space. Peter thinks that it should be done in linear space, and that it doesn't really make sense to average these quantities anyway. This isn't used in hazard calculations (which use getExceedProbabilities). I see the options as:
- leave as is (log space averaging) - probably least desireable
- switch to linear space averaging
- have methods throw an UnsupportedOperationException?
Note: See
TracTickets for help on using
tickets.
leaving open to keep discussion open. not an issue as IMR's are currently used which averages exceedence probabilities instead of means/std devs.
