Apache Spark reassigned SPARK-12230: ------------------------------------ Assignee: Apache Spark > WeightedLeastSquares.fit() should handle division by zero properly if > standard deviation of target variable is zero. > -------------------------------------------------------------------------------------------------------------------- > > Key: SPARK-12230 > URL: https://issues.apache.org/jira/browse/SPARK-12230 > Project: Spark > Issue Type: Bug > Components: ML > Reporter: Imran Younus > Assignee: Apache Spark > Priority: Trivial > > This is a TODO in WeightedLeastSquares.fit() method. If the standard > deviation of the target variablel is zero, then the regression is > meaningless. I think the fit() method should inform the user and exit nicely. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
