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, where p in [0,1]
Provides utilities for descriptive statistics, like the mean and variance.
