[Impala-ASF-CR] IMPALA-12794: Average Independent Variable Calculator: regr avgx() support in Impala
pranav.lodha@cloudera.com has uploaded this change for review. ( http://gerrit.cloudera.org:8080/21009

IMPALA-12794: Average Independent Variable Calculator: regr_avgx()
support in Impala
regr_avgx() is a function designed for statistical analysis and
regression modeling. The primary purpose of this function is to calculate
the average value of the independent variable (X) within a dataset that is
used for linear regression. Linear regression involves predicting a
dependent variable based on the values of one or more independent variables,
and understanding the average value of the independent variable can be
crucial for interpreting and validating the regression model.
Users can incorporate this function into their regression workflows to gain
insights into the central tendency of the independent variable, aiding in the
interpretation of regression coefficients and the overall performance of the
regression model.
Testing:
The functions are extensively tested and cross-checked with Hive.
The tests can be found in aggregation.test.
