Which of the following is NOT a time-series model?
a. exponential smoothing
b. naive approach
c. multiple regression
d. moving average
Homework Answers
Answer: (c) Multiple regression
Explanation: Quantitative forecasting methods are categorized as: Time-series models and Regression models. Naive approach, Moving Average (simple and weighted) and exponential smoothing (level, trend, seasonality) are all examples of time series models.
