# coxregnode properties #

![Cox node icon](https://dataplatform.cloud.ibm.com/docs/content/wsd/nodes/scripting_guide/clementine/images/cox_reg_node_icon.png)The Cox regression node enables you to build a survival model for time\-to\-event data in the presence of censored records\. The model produces a survival function that predicts the probability that the event of interest has occurred at a given time (*t*) for given values of the input variables\.
