logSumExp: Funktion to compute log(sum(exp(x))

Description

Funktion to compute log(sum(exp(x))

Usage

logSumExp(x, mean = F)

Arguments

x

values

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
