> claims that:

> 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)").
> {quote}
> h2. 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.
> h2. 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?
