Tcl script to generate simulated datasets and use these to estimate the F-test probability for adding a model component.
Syntax: simftest <model_comp> <niter>
This script runs <niter> sets of simulated datasets to estimate the F-test probability for adding the additional model component number <model_comp>. Before running this script the model should be set up including the additional component to be tested. The script will create temporary files model0.xcm and model1.xcm.
