CUSUM Analysis Tool (CAT) 2.2 (last updated 21 March 2002)
This software implements the CUSUM-type method for monitoring environmental variables developed by Manly and MacKenzie (2000) .

CAT is no longer supported due to the expiration of Darryl's contract with the University of Otago.
Contact Darryl if you have any questions regarding CAT.

Program PRESENCE (last updated 2 December 2002)
This software estimates the probability a site is occupied by a species (and related parameters), given that the species will not always be detected with certainty, even when present.  The method is detailed in MacKenzie et al. (2002) .
Run setup.exe once you've downloaded PRESENCE.zip .  Help files have been included and updates will be made available seperately as they are completed.  Look here for a list of new features and bug fixes.
