Sum Function

Contents Index

The Sum function returns the sum of the argument variables which have nonmissing values. Examples:

total=Sum(x, y, z);
total=Sum(of x1-x10);
total=Sum(of x y z);

The first and last example assign total the sum of the variables x, y, and z which have nonmissing values. Note the differences in syntax. The last example returns the sum of the variables among x1, ..., x10 which have nonmissing values.
