Fonction ks_2samp - module scipy.stats.mstats

Signature de la fonction ks_2samp

def ks_2samp(data1, data2, alternative='two-sided', mode='auto') 

Description

ks_2samp.__doc__

    Computes the Kolmogorov-Smirnov test on two samples.

    Missing values in `x` and/or `y` are discarded.

    Parameters
    ----------
    data1 : array_like
        First data set
    data2 : array_like
        Second data set
    alternative : {'two-sided', 'less', 'greater'}, optional
        Indicates the alternative hypothesis.  Default is 'two-sided'.
    mode : {'auto', 'exact', 'asymp'}, optional
        Defines the method used for calculating the p-value.
        The following options are available (default is 'auto'):

          * 'auto' : use 'exact' for small size arrays, 'asymp' for large
          * 'exact' : use approximation to exact distribution of test statistic
          * 'asymp' : use asymptotic distribution of test statistic

    Returns
    -------
    d : float
        Value of the Kolmogorov Smirnov test
    p : float
        Corresponding p-value.
