CommandsStatsExpCDFOn this pageStatsExpCDF StatsExpCDF (x, µ, σ) The StatsExpCDF function returns the exponential cumulative distribution function F(x;μ,σ)=1−exp(−x−μσ),\displaystyle F(x ; \mu, \sigma)=1-\exp \left(-\frac{x-\mu}{\sigma}\right),F(x;μ,σ)=1−exp(−σx−μ), where x >= µ and σ > 0. It returns NaN for σ = 0. See Also Statistical Analysis, StatsExpPDF, StatsInvExpCDF
