sumDlogNorm: Sum log-likelihoods of i.i.d. lognormal.

In serrsBayes: Bayesian Modelling of Raman Spectroscopy

Sum log-likelihoods of i.i.d. lognormal.

Description

This is an internal function that is only exposed on the public API for unit testing purposes.

Usage

sumDlogNorm(x, meanlog, sdlog)

Arguments

x	Vector of i.i.d. lognormal random varibles
meanlog	mean of the distribution on the log scale
sdlog	standard deviation on the log scale

Details

The sum of the log-likelihoods (log of the product of the likelihoods) for independent, identically-distributed, lognormal random variables. Note: this Rcpp function is thread-safe, unlike the equivalent alternatives.

Value

log-likelihood of x

See Also

sum(dlnorm(x, meanlog, sdlog, log=TRUE))

Examples

x <- rlnorm(100)
sumDlogNorm(x,0,1)
