In antarctic-humpback-2019-assessment/HumpbackSIR: Use Sample-Importance-Resampling to Estimate Southern Humpback Abundance

Adjusted lognormal likelihood from Zerbini et al. 2011 (eq. 5)

Description

dlnorm_zerb returns the density for the adjusted log normal distribution whose logarith has mean equal to meanlog and standard deviation equal to sdlog: $$f\left(x\right) = \frac1\sigma * x exp \left( \frac \left( ln\left( x \right) - \mu \right) ^ 2 2 \sigma^2 \right)$$

Usage

dlnorm_zerb(x, meanlog, sdlog, return_log = TRUE)

Arguments

x	vector of quantiles.
meanlog	mean of the distribution on the log scale with a default value of 0.
sdlog	standard deviation of the distribution on the log scale with a default value of 1.
log	logical; if TRUE, probabilities p are given as log(p).

Value

A vector of densities.
