zhengruifeng opened a new pull request, #58725: URL: https://github.com/apache/spark/pull/58725
### What changes were proposed in this pull request? This is a follow-up to #58454. This pull request aligns the local column and UDF names in `DecisionTreeRegressionModel.transform` with the other tree regression models and removes the unused `predictVariance` method. The variance prediction logic was moved directly into the transform UDF by #58454. ### Why are the changes needed? The old helper became unused after the transform closure optimization, and consistent local names make the related tree regression transform implementations easier to compare and maintain. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? The following checks passed: ``` build/sbt mllib/compile git diff --check upstream/master...HEAD ``` Changed-file line-length and non-ASCII checks also passed. ### Was this patch authored or co-authored using generative AI tooling?
