scipy.special.inv_boxcox#
- scipy.special.inv_boxcox(y, lmbda, out=None) = <ufunc 'inv_boxcox'>#
- Compute the inverse of the Box-Cox transformation. - Find - xsuch that:- y = (x**lmbda - 1) / lmbda if lmbda != 0 log(x) if lmbda == 0 - Parameters:
- yarray_like
- Data to be transformed. 
- lmbdaarray_like
- Power parameter of the Box-Cox transform. 
- outndarray, optional
- Optional output array for the function values 
 
- Returns:
- xscalar or ndarray
- Transformed data. 
 
 - Notes - Added in version 0.16.0. - Examples - >>> from scipy.special import boxcox, inv_boxcox >>> y = boxcox([1, 4, 10], 2.5) >>> inv_boxcox(y, 2.5) array([1., 4., 10.])
