Dif function
WebThe DIF function works the same way but returns the difference between the current argument and the remembered value. (LAG and DIF return a missing value the first time the function is called.) A true lag function does not return the value of the argument for the "previous call," as do the DATA step LAG and DIF functions. Instead, a true lag ... WebThe DIF functions, DIF1, DIF2, ..., DIF100, return the first differences between the argument and its n th lag. DIF1 can also be written as DIF. DIF n is defined as DIF n ( x)= x-LAG n ( x). For details about storing and ...
