Table 2 Probability functions for different distributions

From: The mobility laws of location-based games

Distribution

Probability function P(x)

Power law

\(x^{-\alpha }\)

Truncated power law

\(x^{-\alpha }e^{-\lambda x}\)

Exponential

\(e^{-\lambda x}\)

Stretched exponential

\(x^{\beta -1}e^{-\lambda x^{\beta }}\)

Log-normal

\(\frac{1}{x}\exp [-\frac{(\ln x-\mu )^{2}}{2\sigma ^{2}}]\)
