Graph of lognormal distribution

WebLogNormalDistribution [μ, σ] represents a continuous statistical distribution supported over the interval and parametrized by a real number μ and by a positive real number σ that together determine the overall shape of its probability density function (PDF). Depending on the values of σ and μ, the PDF of a lognormal distribution may be either unimodal with … WebA lognormal distribution graph drawn on that coordinate grid will appear by straight line so far as will be expressed the dependence t on lnδ, which according to Eq. (1.10) is linear ( Fig. 1.20 ), while a density distribution of particle size represents a bell-shaped curve centered at δ = δ 50 ( Fig. 1.21 ).
