Parameter Description: Type Of Shape
The shape of the dose-response relationship over the treatment groups.
This can be either "linear", "sigmoidEmax", or "userDefined".
If "sigmoidEmax" is selected, "gED50" and "slope" has to be entered
to specify the ED50 and the slope of the sigmoid Emax model.
For "linear" and "sigmoidEmax", "muMaxVector" specifies the range
of effect sizes for the treatment group with highest response.
If "userDefined" is selected, "effectMatrix" has to be entered.
