SAS A00-226 Sample Questions:

01. Which two statements are true regarding the use of the IMPVAR statement to create implicit variables?
(Choose two.)
a) The number of IMPVAR statements cannot exceed the number of declared variables.
b) The IMPVAR statement is optional, but can reduce computational overhead.
c) The implicit variable(s) created in the IMPVAR statement cannot be directly referenced in the objective function.
d) The IMPVAR statement allows complex expressions to be built and referenced so they do not need to be repeated each time they are used.

08. As the exponential smoothing coefficient decreases towards 0, what happens to the emphasis on the most recent values?
a) The emphasis increases.
b) The emphasis decreases.
c) The emphasis stays the same.
d) The emphasis is not related to the exponential smoothing coefficient.
09. In order to correctly interpret the Cross Correlation Function (CCF) plot, which statement is true regarding the input variable in an ARMAX model?
a) The input variable must be stochastic white noise.
b) The input variable must be deterministic white noise.
c) The input variable must contain a linear trend.
d) The input variable must contain autocorrelation.
10. Which statement is true about Net Information Value (NIV)?
