# 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.
