WebAug 30, 2024 · So to work out the discrete distribution we take the values either side of an integer. They'll be a normalising constant as well. For the CTN case, the log-likelihood is just a product of dlnorm (), which is easier and faster. "Safe" is a hard word to define. For this data, the CTN and discrete give visually the same fit. But neither fit well. WebIn this case, DW corresponds to a geometric distribution with p=1-q. Value ddw gives the density, pdw gives the distribution function, qdw gives the quantile function, and rdw generates random samples from a DW distribution with parameters q and beta.
