JOB_ID ID SALARY SLOPE INTCPT RSQR COUNT AVGX AVGY REGR_INTERCEPT(SYSDATE-hire_date, salary) The sections that follow on the individual linear regression functions contain examples of the aggregate form of these functions. The analytic form of these functions can be useful when you want to use regression statistics for calculations such as finding the salary predicted for each employee by the model. The following example provides a comparison of the various linear regression functions used in their analytic form. The following examples are based on the sample tables sh.sales and sh.products. REGR_COUNT(expr1, expr2) * COVAR_POP(expr1, expr2) REGR_SXY makes the following computation after the elimination of null ( expr1, expr2) pairs: REGR_COUNT(expr1, expr2) * VAR_POP(expr1) REGR_SYY makes the following computation after the elimination of null ( expr1, expr2) pairs: REGR_COUNT(expr1, expr2) * VAR_POP(expr2) REGR_SXX makes the following computation after the elimination of null ( expr1, expr2) pairs: REGR_SXY, REGR_SXX, REGR_SYY are auxiliary functions that are used to compute various diagnostic statistics. It makes the following computation after the elimination of null ( expr1, expr2) pairs: REGR_AVGY evaluates the average of the dependent variable ( expr1) of the regression line. REGR_AVGX evaluates the average of the independent variable ( expr2) of the regression line. POWER(CORR(expr1,expr),2) if VAR_POP(expr1) > 0 andĪll of the remaining regression functions return a numeric data type and can be null: VAR_POP( expr1) and VAR_POP( expr2) are evaluated after the elimination of null pairs. The return value is a numeric data type and can be null. REGR_R2 returns the coefficient of determination (also called R-squared or goodness of fit) for the regression. REGR_COUNT returns an integer that is the number of non-null number pairs used to fit the regression line. After the elimination of null ( expr1, expr2) pairs, it makes the following computation:ĪVG(expr1) - REGR_SLOPE(expr1, expr2) * AVG(expr2) REGR_INTERCEPT returns the y-intercept of the regression line. After the elimination of null ( expr1, expr2) pairs, it makes the following computation: REGR_SLOPE returns the slope of the line. Oracle computes all the regression functions simultaneously during a single pass through the data.Įxpr1 is interpreted as a value of the dependent variable (a y value), and expr2 is interpreted as a value of the independent variable (an x value). Oracle applies the function to the set of ( expr1, expr2) pairs after eliminating all pairs for which either expr1 or expr2 is null.
