Link Function

Use this option to specify the Link function to be applied for fitting the generalized linear model.

To Specify a Link Function:

Select the appropriate function using the drop-down menu.

If no function is specified, the following default link functions are applied:

Data Distribution	Default Link Function
Beta	Logit
Binary	Logit
Binomial	Logit
Exponential	Log
Gamma	Log
Gaussian/Normal	Identity
Generalized Poisson	Log
Geometric	Log
Inverse Gaussian	Power with Exponent -2
Lognormal	Identity
Multinomial	Cumulative Logit (for Ordinal Data) or Generalized Logit (for Nominal Data)
Negative Binomial	Log
Poisson	Log
t	Identity
