CommandsStatsDExpCDFOn this pageStatsDExpCDF StatsDExpCDF (x, µ, σ) The StatsDExpCDF function returns the double-exponential cumulative distribution function F(x;μ,σ)={exp(x−μσ) when x<μ1−12exp(−∣x−μσ∣) when x≥μF(x ; \mu, \sigma)=\left\{\begin{array}{ll} \displaystyle \exp \left(\frac{x-\mu}{\sigma}\right) & \text { when } x<\mu \\ \\ \displaystyle 1-\frac{1}{2} \exp \left(-\left|\frac{x-\mu}{\sigma}\right|\right) & \text { when } x \geq \mu \end{array}\right.F(x;μ,σ)=⎩⎨⎧exp(σx−μ)1−21exp(−σx−μ) when x<μ when x≥μ where σ>0. It returns NaN if σ=0. See Also Statistical Analysis, StatsDExpPDF, StatsInvDExpCDF
