logsumexp R Documentation
Calculate the logarithm of the sum of the exponentials of the arguments
Description
Calculation of the log of the sum of exponential of x, but avoids computational
underflow / overflow
Usage
logsumexp(x)
Arguments
x
vector
Value
the logarithm of the sum of the exponentials of elements of x
i.e. returns log(sum(exp(x)))
Examples
x <- c(1000.01, 1000.02)
y1 <- log(sum(exp(x)))
print(y1)
y2 <- logsumexp(x)
print(y2)
