< > Linn said I have problems in generating a variable I need in my calculations: I need to generate a variable X2 as a mean of the variable X1 and the next x1[_n+1] til X1[_n+8]. Thus the value of X2 is going to change for each observation in the samlpe Can this be done using egen? As this variable X2 will be changed it is not very practical to calculate the mean by typing X2=(X1 + X1[_n+1] etc..)/n. tssmooth ma x2 = x1, window(0 1 8)
