Transformer
LogTransformer
Natural logarithm transformation.
The Natural logarithm transformation can be used to make the data more normally distributed and stabilize its variance.
Transforms each data point x to log(scale *(x+offset))
Schnellstart
python
from sktime.transformations.boxcox import LogTransformer
estimator = LogTransformer(offset=0, scale=1)Parameter(2)
- offsetfloat, default = 0
- Additive constant applied to all the data.
- scalefloat, default = 1
- Multiplicative scaling constant applied to all the data.
