Summary: Implement PowerTransform
Key: SPARK-31180
URL: https://issues.apache.org/jira/browse/SPARK-31180
Project: Spark
Issue Type: Improvement
Components: ML
Affects Versions: 3.1.0
Reporter: zhengruifeng
{color:#5a6e5a}Power transforms are a family of parametric, monotonic
transformations
{color}{color:#5a6e5a}that are applied to make data more Gaussian-like. This is
useful for
{color}{color:#5a6e5a}modeling issues related to heteroscedasticity
(non-constant variance),
{color}{color:#5a6e5a}or other situations where normality is desired.{color}
