Compressmodel

Compressmodel

Purpose

Remove references to unused variables from a model.

Synopsis

[cmodel,msg] = compressmodel(model,include)

Description

COMPRESSMODEL will remove any references in a model to excluded variables. This permits the application of the model to new data in which unused variables have been hard-excluded (i.e. previously removed or not collected).

Inputs

• model = model to compress

Optional Inputs

• include = Index range of variables to include. If not provided, compressmodel will keep only those variables which are explictly marked as included in the original data.

Outputs

• cmodel = the compressed model
• msg = any warning messages reported during compression.

Although compression will work on most models, some preprocessing methods and some model types may not compress correctly. In these cases, a warning will be given and reported in the output (msg).
