GenLin Node Field Options

In addition to the target, input, and partition custom options typically offered on modeling node Fields tabs (see Modeling Node Fields Options ), the GenLin node offers the following extra functionality.

Use weight field. The scale parameter is an estimated model parameter related to the variance of the response. The scale weights are "known" values that can vary from observation to observation. If the scale weight variable is specified, the scale parameter, which is related to the variance of the response, is divided by it for each observation. Records with scale weight values that are less than or equal to 0 or are missing are not used in the analysis.

Target field represents number of events occurring in a set of trials. When the response is a number of events occurring in a set of trials, the target field contains the number of events and you can select an additional variable containing the number of trials. Alternatively, if the number of trials is the same across all subjects, then trials may be specified using a fixed value. The number of trials should be greater than or equal to the number of events for each record. Events should be non-negative integers, and trials should be positive integers.
