SAS is so powerful that it can understand any type of data and it can access data from any software and any format. Logical operation can also be performed in SAS by using if –then statements. SAS runs all statements in a loop, step by step, and executes the program very quickly. ODS...
If we have not mentioned the retain statement, then the SAS would be returned, and the variables would reset at the beginning of the data step. Retain statement will keep the value once we assign the serial number or row the index number with the data step. Suppose we have a group varia...
Both types of trees are referred to as decision trees because the model is expressed as a series of if-then statements. The predictor variables for tree models can be categorical or continuous. The model is based on a partition of the predictor space into nonoverlapping segments, which ...

When used without a FILE statement, PUT statements write values in the log, a handy place for them to be for debugging. The following statement tells SAS to print the values of selected variables for every observation with a missing value for Angle. IF Angle = . THEN PUT Weight= Lift3=...
