VPERCRANK(value,variable[,filter]) returns the percentile rank of a value.
In the absense of ties in the data, this function is the inverse of the VPERCENTILE function.
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.
