Fonction ttest_ind - module scipy.stats.mstats

Signature de la fonction ttest_ind

def ttest_ind(a, b, axis=0, equal_var=True) 

Description

ttest_ind.__doc__

    Calculates the T-test for the means of TWO INDEPENDENT samples of scores.

    Parameters
    ----------
    a, b : array_like
        The arrays must have the same shape, except in the dimension
        corresponding to `axis` (the first, by default).
    axis : int or None, optional
        Axis along which to compute test. If None, compute over the whole
        arrays, `a`, and `b`.
    equal_var : bool, optional
        If True, perform a standard independent 2 sample test that assumes equal
        population variances.
        If False, perform Welch's t-test, which does not assume equal population
        variance.

    Returns
    -------
    statistic : float or array
        The calculated t-statistic.
    pvalue : float or array
        The two-tailed p-value.
