Apache Spark reassigned SPARK-7241:
-----------------------------------
Assignee: Burak Yavuz (was: Apache Spark)
> Pearson correlation for DataFrames
> ----------------------------------
>
> Key: SPARK-7241
> URL: https://issues.apache.org/jira/browse/SPARK-7241
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Reporter: Xiangrui Meng
> Assignee: Burak Yavuz
>
> This JIRA is for computing the Pearson linear correlation for two numerical
> columns in a DataFrame. The method `corr` should live under `df.stat`:
> {code}
> df.stat.corr(col1, col2, method="pearson"): Double
> {code}
> `method` will be used when we add other correlations.
> Similar to SPARK-7240, UDAF will be added later.
