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

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.
