WebSome statisticians suggest never using Bartlett's test. It is too sensitive to minor differences that wouldn't really affect the overall variance. So if the difference in variances is not huge, and especially if your sample sizes are equal (or nearly so), you might be safe just ignoring Barlett's test. Some suggest using Levene's median test ... Web5 apr. 2005 · The choice of the gamma distribution is partly for mathematical convenience but also because the exponential distribution (and hence the NHPP) is a special case, and the parameterization by (μ,τ) is a convenient way to model dispersion: τ = 1 implies the NHPP, whereas τ > 1 or τ < 1 implies more or less variation in interarrival times than in …
