WebOct 8, 2024 · Instead, these versions of Excel use the equivalent function EXPONDIST. Observation: The exponential distribution is equivalent to the gamma distribution with α = 1 and β = 1/λ. Thus, EXPON.DIST (x, λ, cum) = GAMMA.DIST (x, 1, 1/λ, cum). There is no EXPON.INV (p, λ) function in Excel, but GAMMA.INV (p, 1, 1/λ) or –LN (1–p)/λ or the ...
