CommandsStatsNormalCDFOn this pageStatsNormalCDF StatsNormalCDF (x, µ, σ) The StatsNormalCDF function returns the normal cumulative distribution function. F(x,μ,σ)=12+12erf(x−μσ2),\displaystyle F(x, \mu, \sigma)=\frac{1}{2}+\frac{1}{2} \operatorname{erf}\left(\frac{x-\mu}{\sigma \sqrt{2}}\right),F(x,μ,σ)=21+21erf(σ2x−μ), where erf is the error function.
