statsmodels.stats.weightstats.CompareMeans.from_data

classmethod CompareMeans.from_data(data1, data2, weights1=None, weights2=None, ddof1=0, ddof2=0)

construct a CompareMeans object from data

Parameters:

• data1 (array_like, 1-D or 2-D) – compared datasets

• data2 (array_like, 1-D or 2-D) – compared datasets

• weights1 (None or 1-D ndarray) – weights for each observation of data1 and data2 respectively, with same length as zero axis of corresponding dataset.

• weights2 (None or 1-D ndarray) – weights for each observation of data1 and data2 respectively, with same length as zero axis of corresponding dataset.

• ddof1 (int) – default ddof1=0, ddof2=0, degrees of freedom for data1, data2 respectively.

• ddof2 (int) – default ddof1=0, ddof2=0, degrees of freedom for data1, data2 respectively.

Return type:

A CompareMeans instance.
