Cumulative intensity function
WebFeb 16, 2024 · The generalized F distribution with P=0 is equivalent to the generalized gamma distribution dgengamma, so that dgenf (x, mu, sigma, Q, P=0) equals dgengamma (x, mu, sigma, Q). The generalized gamma reduces further to several common distributions, as described in the GenGamma help page. The generalized F distribution includes the … Webwhere W (t) is the cumulative intensity function (CIF) that is a function of time. Assuming that the system is continuously impacted during its operation, the level of each impact is related to WCs. The probability of failure is related to the cumulative damage within a certain period. The increment of cumulative damage means an increased ...
