simpops.mac is a free script written by Daniel Barker and Richard Sibly. simpops.mac uses the theta-logistic model of population regulation to simulate observed population time series, with environmental perturbation and measurement error.
simpops.mac is a Minitab macro and requires Minitab statistical software to run. We have used it under Minitab version 14.20 for Windows.
Open simpops.mac in a text editor (e.g. Notepad). Read and follow the instructions given in a long comment at the top of the script.
The current version is simpops.mac 1.0.

Users of simpops.mac may also find it helpful to download genlogistic.ssc.
With slight modification, genlogistic.ssc may be used to analyse the output of simpops.mac.
