Hi all,
I am trying to find formulae for calculating the overlap between two normally distributed populations.
There are some online calculators specifically for this but they do not have the resolutinion i require.
So for M1,?1 and M2,?2, (where M is Mean and ? is StDev) what formula will give me the probability of samples from these populations overlapping.
Im trying to find the % interferance fit between an OD and ID
I have been using JMP so far as a stop gap but i know this is not entirely accurate, the method below is what im using
by finding the % of Group 2 below the point M1+3(?1) and vise versa, then multiplying the two %
M+3(?) still leaves 0.15% of the population unacounted for and i want a more accurate result.
Your comments on a better fast method aswell as the formuala are welcome and appraciated
Thanks
