Extra named parameters required for initializing certain distributions.
If t-distribution is selected, an additional parameter ( If quantile is selected then the quantile to estimate may be specified using the
named parameter If the tweedie distribution is selected the power-law specifying the distribution
may be set via the named parameter: If a Cox Partial Hazards model is selected a number of additional parameters are required, these are:
Finally, if the pairwise distribution is selected a number of parameters also need to be
specified. These parameters are
