Fitting a normal distribution in excel
WebThe geometric distribution parameter can be estimated as p = 1/ (1–x̄). The Gumbel distribution parameters can be estimated by β = s√6/π and μ = x̄ – βγ where γ is the Euler-Mascheroni constant with a value approximately equal to .577215665 (see Gumbel Distribution ). The Logistic distribution parameters are estimated by μ = x̄ and β = s√3/π. WebIn statistics, we have a term called a lognormal distribution calculated to determine the distribution of a variable whose logarithm is normally distributed. The original formula is …
