WebApr 24, 2024 · Proof Note that the geometric distribution is always positively skewed. Moreover, skew(N) → ∞ and kurt(N) → ∞ as p ↑ 1. Suppose now that M = N − 1, so that M (the number of failures before the first success) has the geometric distribution on N. Then E(M) = 1 − p p var(M) = 1 − p p2 skew(M) = 2 − p √1 − p kurt(M) = p2 1 − p WebThe geometric series is inserted for the factor with the substitution x = 1- (√u )/ε , Then the square root can be approximated with the partial sum of this geometric series with common ratio x = 1- (√u)/ε , after solving for √u from the result of evaluating the geometric series Nth partial sum for any particular value of the upper ...
