init.value |
number in (0, 0.5) representing a percentile of the null distribution to use as starting value |
null.mean |
estimated mean of null distribution (usually found with locfdrFit) |
null.sd |
estimated standard deviation of null distribution (usually found with locfdrFit) |
null.prop |
estimated proportion of statistics that came from the null distribution |
vals |
vector of all the observed values from the mixture distribution |
up |
if TRUE, find mean of overexpressed statistics, otherwise find mean of underexpressed statistics |
For experienced users/debugging only. Calls
find.mean.up
if up=TRUE, else calls
find.mean.down
. Most users should use
getParams
rather than find.mean
.
If numerical method succeeds, a list with elements
m
|
estimated mean of the underexpressed distribution, and |
p |
the percentile of the null distribution used to find this mean |
If numerical method fails, a list with elements
m |
mean of underexpressed distribution, as estimated by the 5th percentile of the estimated null distribution |
s |
standard deviation of underexpressed distribution, as estimated by the standard deviation of the null distribution |
