Description
Problem description
The org.apache.spark.sql.functions documentation claims that:
(...) You can find the entire list of functions at SQL API documentation.
(...)
regr_count is an example of a function that is built-in but not defined here, because it is less commonly used. To invoke it, use expr("regr_count(yCol, xCol)").
Issue 1
I had to roam a little bit to arrive at: https://spark.apache.org/docs/latest/api/sql/index.html. Is this the "SQL API documentation" to which the text refers? If so, I suggest adding this link there.
Issue 2
The documentation cites the function 'regr_count', but I couldn't find its documentation in the SQL API https://spark.apache.org/docs/latest/api/sql/index.html. The issue https://issues.apache.org/jira/browse/SPARK-23907 is related to this function. Where is the documentation for this function?
