Statistics¶
Order statistics¶
amin (a[, axis, out, keepdims]) |
Return the minimum of an array or minimum along an axis. |
amax (a[, axis, out, keepdims]) |
Return the maximum of an array or maximum along an axis. |
nanmin (a[, axis, out, keepdims]) |
Return minimum of an array or minimum along an axis, ignoring any NaNs. |
nanmax (a[, axis, out, keepdims]) |
Return the maximum of an array or maximum along an axis, ignoring any NaNs. |
ptp (a[, axis, out]) |
Range of values (maximum - minimum) along an axis. |
percentile (a, q[, axis, out, …]) |
Compute the qth percentile of the data along the specified axis. |
nanpercentile (a, q[, axis, out, …]) |
Compute the qth percentile of the data along the specified axis, while ignoring nan values. |

correlate (a, v[, mode]) |
Cross-correlation of two 1-dimensional sequences. |
cov (m[, y, rowvar, bias, ddof, fweights, …]) |
Estimate a covariance matrix, given data and weights. |
Histograms¶
histogram (a[, bins, range, normed, weights, …]) |
Compute the histogram of a set of data. |
histogram2d (x, y[, bins, range, normed, weights]) |
Compute the bi-dimensional histogram of two data samples. |
histogramdd (sample[, bins, range, normed, …]) |
Compute the multidimensional histogram of some data. |
bincount (x[, weights, minlength]) |
Count number of occurrences of each value in array of non-negative ints. |
digitize (x, bins[, right]) |
Return the indices of the bins to which each value in input array belongs. |
