genlinnode properties
The Generalized Linear (GenLin) model expands the general linear model so that the
dependent variable is linearly related to the factors and covariates through a specified link
function. Moreover, the model allows for the dependent variable to have a non-normal distribution.
It covers the functionality of a wide number of statistical models, including linear regression,
logistic regression, loglinear models for count data, and interval-censored survival models.
Example
node = stream.create("genlin", "My node")
node.setPropertyValue("model_type", "MainAndAllTwoWayEffects")
node.setPropertyValue("offset_type", "Variable")
node.setPropertyValue("offset_field", "Claimant")

field | GenLin models require a single target field which must be a nominal or flag field, and one or more input fields. A weight field can also be specified. See Common modeling node properties for more information. |
