Funktion to compute log(sum(exp(x))
Description
Funktion to compute log(sum(exp(x))
Usage
logSumExp(x, mean = F)
Arguments
x
values at log scale
mean
logical, determines whether the mean should be used instead of the sum
Details
This function computes log(sum(exp(x)), using the offset trick to avoid numeric overflow, see, e.g. http://jblevins.org/notes/log-sum-exp. The mean option allows calculating logMeanExp
