function is “bell”-shaped, and is known as the Gaussian function or bell

发帖数: 15 | 35 We treat the 0 variance/covariance case as normal.
X is a random vector with n components.
Then X is multivariate normal if and only if
LX is univariate normal, for every 1 x n vector L.
See any general multivariate statistics textbook.
Therefore, the sum of two normals (indep. or not) is still normal if
we choose L=(1, 1). |

1. Data step and proc step 不能nested. Data step can't be nested in another

2. %IF %THEN %END should be in open mode instead of data step
3. When you compare values in open mode, it has to be macro variables. (see

I still don't understand your last 4 data steps. There is no macro variables
at all. Why put them inside the macro.
