logmeanexp
computes
log mean exp(x_i),
avoiding over- and under-flow in doing so.
1 | logmeanexp(x, se = FALSE)
|
x |
numeric |
se |
logical; give approximate standard error? |
log(mean(exp(x)))
computed so as to avoid over- or underflow.
If se = FALSE
, the approximate standard error is returned as well.
