# Statistical Functions¶

## Order statistics¶

 cupy.amin Returns the minimum of an array or the minimum along an axis. cupy.amax Returns the maximum of an array or the maximum along an axis. cupy.nanmin Returns the minimum of an array along an axis ignoring NaN. cupy.nanmax Returns the maximum of an array along an axis ignoring NaN. cupy.percentile Computes the q-th percentile of the data along the specified axis. cupy.ptp Returns the range of values (maximum - minimum) along an axis.

## Means and variances¶

 cupy.median Compute the median along the specified axis. cupy.average Returns the weighted average along an axis. cupy.mean Returns the arithmetic mean along an axis. cupy.var Returns the variance along an axis. cupy.std Returns the standard deviation along an axis. cupy.nanmedian Compute the median along the specified axis, while ignoring NaNs. cupy.nanmean Returns the arithmetic mean along an axis ignoring NaN values. cupy.nanvar Returns the variance along an axis ignoring NaN values. cupy.nanstd Returns the standard deviation along an axis ignoring NaN values.

## Histograms¶

 cupy.histogram Computes the histogram of a set of data. cupy.histogram2d Compute the bi-dimensional histogram of two data samples. cupy.histogramdd Compute the multidimensional histogram of some data. cupy.bincount Count number of occurrences of each value in array of non-negative ints. cupy.digitize Finds the indices of the bins to which each value in input array belongs.

## Correlations¶

 cupy.corrcoef Returns the Pearson product-moment correlation coefficients of an array. cupy.cov Returns the covariance matrix of an array. cupy.correlate Returns the cross-correlation of two 1-dimensional sequences.
