Hi All,
I have attached SAS Data Set, New_Gold needs to calculate as
If _n_ then .
if _n_=2 then (Obs2-Obs1)^2
if _n_=3 then (obs3-obs2)^2
if _n_=4 then (Obs4-Obs3)^2 etc
As a first step I am using Lag function.
New_Gold=Lag(1_GoldS)
I am getting the follwing error, Please advise.
ERROR 22-322: Syntax error, expecting one of the following: !, !!, &, *, **, +, ',', -, /, <, <=, <>, =, >, ><, >=, AND, EQ, GE, GT, IN, LE, LT, MAX, MIN, NE, NG, NL, NOTIN, OR, ^=, |, ||, ~=.
ERROR 72-185: The LAG function call has too many arguments.
