[I] [Epic] Support for Regression Functions [datafusion]
Weijun-H opened a new issue, #12234:
URL: https://github.com/apache/datafusion/issues/12234
### Is your feature request related to a problem or challenge?
We need to implement a set of regression functions to support statistical analysis in our data processing workflows. These functions will enable users to perform regression analysis directly within their queries, allowing for more robust and comprehensive data exploration and reporting.
Functions to be Supported:
- [ ] `regr_avgx(y, x)`
- [ ] `regr_avgy(y, x)`
- [ ] `regr_count(y, x)`
- [ ] `regr_intercept(y, x)`
- [ ] `regr_r2(y, x)`
- [ ] `regr_slope(y, x)`
- [ ] `regr_sxx(y, x)`
- [ ] `regr_sxy(y, x)`
- [ ] `regr_syy(y, x)`

Looks like all of their functions have been implemented already, docs [here](https://datafusion.apache.org/user-guide/sql/aggregate_functions.html#statistical).
