Design and analysis of accelerated degradation tests for the stability of biological standards II. A flexible...

The accelerated degradation test is commonly used to predict the stability of a biological standard during long-term storage at low temperature. A flexible computer program is described which has been written to analyse degradation test results by the method of maximum likelihood. In addition to predicting the degradation rate at low temperature, the program furnishes estimates of statistical precision and it carried out a test of goodness of fit of the data to the assumed Arrhenius equation model.
