    Description

      regr_count() returns an integer that is the number of non-null number pairs used to fit the regression line.
      regr_avgx() evaluates the average of the independent variable of the regression line. It computes avg(expr2) after the elimination of null (expr1, expr2).
      regr_avgy() evaluates the average of the dependent variable of the regression line. It computes avg(expr1) after the elimination of null (expr1, expr2).
