VSTEYX function


VSTEYX(variableX,variableY[,filter]) returns the standard error of the predicted y-values in the regression of variableY on variableX. An optional filter can be specified.

The equation for VSTEYX is:

$$ \sqrt{ \frac{1}{n-2} \left[ \sum_{}^{}{(y-\bar{y})^2} - \frac{ \left[ \sum_{}^{}{(x-\bar{x})(y-\bar{y})} \right]^2 } {\sum_{}^{}{(x-\bar{x})^2}} \right]} $$

Note that in comparison with the corresponding Excel function, the order of the X and Y arguments is reversed.


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.
