ValueError: Data must be positive (boxcox scipy)

Question

I\'m trying to transform my dataset to a normal distribution.

0      8.298511e-03
1      3.055319e-01
2      6.938647e-02
3      2.904091e-02
4      7.422441e-0         


        

Answer 1

Rather than normal boxcox, you can use boxcox1p. It adds 1 to x so there won't be any "0" record

from scipy.special import boxcox1p
scipy.special.boxcox1p(x, lmbda)

For more info check out the docs at https://docs.scipy.org/doc/scipy/reference/generated/scipy.special.boxcox1p.html
