Calculate the p-value for Hopkins statistic
Arguments
- x
Observed value of Hopkins statistic
- n
Number of events/points sampled.
Value
A p-value between 0 and 1.
Details
Under null hypothesis of spatial randomness, Hopkins statistic has a
Beta(m,m) distribution, where 'm' is the number of events/points sampled.
This function calculates the p-value for the statistic.
