public CategoricalGenLinModel( double[,] x, CategoricalGenLinModelDistributionParameterModel model )
Use one of the class members from the following table. The lower bound given in the table is the minimum possible value of the response variable:
Model | Distribution | Function | Lower-bound |
---|---|---|---|
0 | Poisson | Exponential | 0 |
1 | Negative Binomial | Logistic | 0 |
2 | Logarithmic | Logistic | 1 |
3 | Binomial | Logistic | 0 |
4 | Binomial | Probit | 0 |
5 | Binomial | Log-log | 0 |
Let be the dot product of a row in the design matrix with the parameters (plus the fixed parameter, if used). Then, the functions used to model the distribution parameter are given by:
Name | Function |
---|---|
Exponential | |
Logistic | |
Probit | (where is the normal cdf) |
Log-log |
