Skew Generalized Error distribution maximum likelihood estimation
Description
Joint maximum likelihood estimation as implemented by fGarch::sgedFit.
Usage
mlsged(x, na.rm = FALSE, ...)
Arguments
x |
a (non-empty) numeric vector of data values. |
na.rm |
logical. Should missing values be removed? |
... |
currently affects nothing. |
Details
For the density function of the Student t-distribution see sged.
