-
astroML.correlation.
two_point
(data, bins, method='standard', data_R=None, random_state=None)[source]¶ Two-point correlation function
- Parameters
- dataarray_like
input data, shape = [n_samples, n_features]
- binsarray_like
bins within which to compute the 2-point correlation. shape = Nbins + 1
- methodstring
“standard” or “landy-szalay”.
- data_Rarray_like (optional)
if specified, use this as the random comparison sample
- random_stateinteger, np.random.RandomState, or None
specify the random state to use for generating background
- Returns
- corrndarray
the estimate of the correlation function within each bin shape = Nbins
