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
