WebIf axis is None, all values in f_obs are treated as a single data set. Default is 0. Returns: chisq float or ndarray. The chi-squared test statistic. The value is a float if axis is None or f_obs and f_exp are 1-D. p float or ndarray. The p-value of the test. The value is a float if ddof and the return value chisq are scalars. WebThe natural logarithm log is the inverse of the exponential function, so that log (exp (x)) = x. The natural logarithm is logarithm in base e. Parameters: xarray_like. Input value. outndarray, None, or tuple of ndarray and None, optional. A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to.
