 The Oracle PL/SQL REGR_INTERCEPT Function      [Return To Index] Jump to:  


In Oracle PL/SQL, REGR_INTERCEPT is a linear regression analytic function which takes two numeric inputs and returns the y-intercept of the regression line according to the calculation shown below:

AVG(x) - REGR_SLOPE( x, y) * AVG( y )

Note that the pairs having any argument's value as NULL are eliminated, but the final result might be NULL as per the above computation.

Example Syntax:


In the syntax, 'x' is referred to as the dependent variable and 'y' is referred to as the independent variable of the Regression Line.

Example Usage:

sql> SELECT deptno, sal, REGR_INTERCEPT(sal, deptno) OVER (partition by deptno) "REGR_INTERCEPT"
FROM employee
