# genlinnode properties #

![GenLin node icon](https://dataplatform.cloud.ibm.com/docs/content/wsd/nodes/scripting_guide/clementine/images/genlinnodeicon.png)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\.
