mllgamma {univariateML} | R Documentation |
Log-gamma distribution maximum likelihood estimation
Description
The maximum likelihood estimate of shapelog
and ratelog
are calculated
by calling mlgamma()
on the transformed data.
Usage
mllgamma(x, na.rm = FALSE, ...)
Arguments
x |
a (non-empty) numeric vector of data values. |
na.rm |
logical. Should missing values be removed? |
... |
passed to |
Details
For the density function of the log normal distribution see Loggamma.
