Cure rate based step-stress model

WebSep 11, 2024 · This research mainly aims to develop a generalized cure rate model, estimate the proportion of cured patients and their survival rate, and identify the risk factors associated with infectious diseases. The generalized cure rate model is based on bounded cumulative hazard function, which is a non-mixture model, and is developed using a two … WebThe cumulative damage model allows you to analyze data from accelerated life tests with time-dependent stress profiles. The step-stress model, as discussed in , and the related ramp-stress model are typical cases of time-dependent stress tests. In these cases, the stress load remains constant for a period of time and then is stepped/ramped into ...
