Returns covariance between two vectors.
Returns covariance between two vectors.
Note: Will happily compute covariance between vectors of different lengths by truncating the longer vector.
Returns both means and covariance between two vectors.
Returns both means and covariance between two vectors. Single pass algorithm.
Note: Will happily compute covariance between vectors of different lengths by truncating the longer vector.
Returns the estimate of the data at p * it.size after copying and sorting, where p in [0,1].
Returns the estimate of a pre-sorted array at p * it.size, where p in [0,1].
Returns the estimate of a pre-sorted array at p * it.size, where p in [0,1].
Note: Result is invalid if the input array is not already sorted.
Provides utilities for descriptive statistics, like the mean and variance.
