PriProbit analysis program

PriProbit was developed by Dr. Masayuki Sakuma at Kyoto University in Japan. This program is for probit analysis of preference data, such as might be obtained in behavioral studies, but can also be used for analysis of dose-mortality data from bioassay studies. This program is supported by Dr. Sakuma, not USDA. USDA provides the program at this site only for the convenience of our customers. USDA does not guarantee the suitability of the program for data analysis. Questions about PriProbit and requests for support for PriProbit should be addressed to Dr. Sakuma at The method upon which the program is based is described in:  Sakuma, M. 1998. Probit analysis of preference data. Appl. Entomol. Zool. 33: 339-347.
