initial values in wlogit/wprobit

[Jorge]

Sometimes the user knows initial values for the parameter in a wlogit/wprobit model but there is no way to specify it in the model constructor. Although there es way of doing it:

Matrix wProbit::_.param::initial := ...

it is desirable to provide the initial value at model construction:

QltvRespModel::@WgtProbit wProbit = [[
 Text output.name = name;
 Set input.name = parameterIdentifiers;
 VMatrix y = Mat2VMat(outputData);
 VMatrix X = Mat2VMat(inputData);
 VMatrix w = Mat2VMat(weightData);
 Set prior = priorInfo;
 Matrix initial = ...
]]
