VINTERCEPT function
Description
VINTERCEPT(variableX,variableY[,filter]) returns the intercept of the regression line of the independent variable variableX and the dependent variable variableY. An optional filter can be specified.
The equation for VINTERCEPT a is:
where b, the slope, is calculated as:
Note that in comparison with the corresponding Excel INTERCEPT function, the order of the X and Y arguments is reversed.
Note
This function calculates a statistic on a variable. Be careful when you use this function in cells of the columns that correspond to the variable, because this actually adds a value to the variable which can lead to unexpected and faulty results. You can exclude the cell to avoid this.
