As you can see in the documentation for the SUM function here, the SUM function "Returns the sum of the nonmissing arguments.", i.e. the sum function ignores the missing value. On the other hand, when you use a missing value with an arithmetic operator (+, - etc), it returnsa miss...
6. 18 Correct answer: d You do not need to name the variables in a VAR statement if you specify them in the SUM statement, but you can. If you choose not to name the variables in the VAR statement as well, then the SUM statement determines the order of the variables in the output...
A previous article discusses the MakeString function, which you can use to convert an IML character vector into a string. This can be very useful. When I originally wrote the MakeString function, I was disappointed that I could not vectorize the computation. Recently, I learned about the COM...

3. The COALESCE function The COALESCE function does the magic to combine multiple rows into a single one with any non-missing value. In this example, there are two rows of SSNs, and supposedly they should be identical each other. However, some of them are missing due to input errors or...
predicted based on known value of other variables. The response variable is categorical, meaning it can assume only a limited number of values. With binary logistic regression, a response variable has only two values such as 0 or 1. In multiple logistic regression, a response variable can have...
