WebJan 6, 2012 · $\begingroup$ Perhaps I am missing something, but if you already know of a test for testing the fit of the distribution and all you need to know are the values of the theoretical distribution, then you could simply use the maximum likelihood estimators of the parameters of the gamma distribution on your data to get estimates of the parameters. … WebXLSTAT offers two fitting methods: Moments for distribution fitting. This simple method uses the definition of the moments of the distribution as a function of the parameters to determine the latter. For most distributions, …
WebThe gamma is a flexible life distribution model that may offer a good fit to some sets of failure data. It is not, however, widely used as a life distribution model for common failure mechanisms. The gamma does arise naturally as the time-to-first fail distribution for a system with standby exponentially distributed backups.
