CommandsStatsNormalPDFOn this pageStatsNormalPDF StatsNormalPDF (x, µ, σ) The StatsNormalPDF function returns the normal probability distribution function. f(x,μ,σ)=1σ2πexp(−(x−μ)22σ2).\displaystyle f(x, \mu, \sigma)=\frac{1}{\sigma \sqrt{2 \pi}} \exp \left(-\frac{(x-\mu)^{2}}{2 \sigma^{2}}\right) .f(x,μ,σ)=σ2π1exp(−2σ2(x−μ)2).
