Log function shape

WitrynaLogarithm is a multivalued function: for each x there is an infinite number of z such that exp (z) = x. The convention is to return the z whose imaginary part lies in (-pi, pi]. For real-valued input data types, log always returns real output. Witryna23 kwi 2024 · The logarithmic series distribution with shape parameter p ∈ (0, 1) is a discrete distribution on N + with probability density function f given by f(n) = 1 − ln(1 − p) pn n, n ∈ N +. f is decreasing with mode n = 1. When smoothed, f is concave upward. Open the Special Distribution Simulator and select the logarithmic series distribution.
