Initial Parameter Estimates for a TVGEV model.
parIni.TVGEV(object, y = NULL)A (possibly incomplete) TVGEV object.
The response, by defaut the response attached to the model.
A vector of initial values.
The model parameters that are inverse-linked to the location parameter are found by using a linear model with a constant error variance. The initial value of the shape parameter(s) being set to zero, which correspond to Gumbel margins, we know that the expectation is approximately \(\mu + 0.577 \sigma\) while the standard deviation is \(\sigma \sqrt{\pi} / 6\)
