question 24

Multiple Choice

The following is the list of MAD statistics for each of the models you have estimated from time-series data: $$\begin{array} { | l | r | } \hline \text { Model } & \text { MAD } \\\hline \text { Linear Trend } & 1.38 \\\hline \text { Quadratic Trend } & 1.29 \\\hline \text { Exponential Trend } & 1.39 \\\hline \text { Second-order Autoregressive } & 0.71 \\\hline\end{array}$$
Based on the MAD criterion, the most appropriate model is

• A) linear trend.
• B) quadratic trend.
• C) exponential trend.
• D) second-order autoregressive.

Definitions:

Conditional Reinforcement

The process by which stimuli that are associated with a primary reinforcer also become reinforcers themselves, often through classical conditioning.

Postreinforcement Pause

A pause in responding that commonly occurs after the delivery of a reinforcer under certain schedules of reinforcement, such as a fixed ratio schedule.

FR-5 Schedule

A fixed-ratio schedule of reinforcement where a response is rewarded only after five instances of the behavior.

FR-15 Schedule

A fixed-ratio schedule of reinforcement where a response is reinforced only after it has been produced 15 times.
