Logistic beta
Witryna7 wrz 2024 · The logistic-beta distribution with known ϕ is a LEF, so it could be used to generate a GLM family, although I have never known anyone to do so. Note that this derivation only works when α + β is known; α + β would not be the dispersion parameter for a logistic-beta GLM.
