Cumulative distribution function value PDF Graph CDF Graph Cumulative density function (CDF) of the lognormal distribution formula: To calculate log-normal distribution quantiles, you can use the following calculator:
The normal PDF of the lognormal distribution is given by: (7.13)f(t)=1σtt2πexp[−12σt2(lnt−μt)2] and CDF is given by: (7.14)F(t)=1σt2π∫0t1θexp[−12(lnθ−μt)2σt22]dθ where h(t) is calculated by the same formula than in the normal distribution, and...

两者的LogNormal 类的基类都是TransformedDistribution,从文档中可了解到,如果概率分布 $P(y)$ 可以表示成一个基础概率分布 $P(x)$ ,以及一个可微可逆的变换 $Y=g(X)$ ,那么可以用通过继承 TransformedDistribution类,将概率分布 $P(x)$ 变换为新的概率分布 $P(y)$。 LogNormal 是满足使用TransformedDistrib...
Binomial distributionPoisson distributionBlack-Scholes formulaIn this chapter, we first introduce normal distribution, lognormal distribution, and their relationship. Then we discuss multivariate normal and lognormal distributions. Finally, we apply both normal......
Lognormal distribution definition We give the definition of the lognormal distribution in terms of its pdf. Namely, the formula for the probability density function of the lognormal distribution reads: where σ and μ are the parameters for lognormal distribution: μ is the scale parameter; and ...
