What a forecaster uses the __ method, she or he assumes that the time series components are changing slowly
Homework Answers
Answer
correct answer is exponential smoothing
In exponential smoothing, more weightage is given to the recent data values as compared to older data values. This is because we assume that the recent data values are better in prediction as compared to older data values
So, we can say that the exponential smoothing shows us that the time series components are changing slowly due to which we given higher weightage to recent data values

3. (10 pts) A certain weather forecaster is correct 80% of the time when he forecasts rain and 90% of the time when he forecasts sun. Given the climate in his area. 30% of his forecasts are for rain and 70% are for sun. Suppose it rained yesterday. What is the probability that yesterday's forecast actually called for rain? a. 0.1987

What is the most difficult problem for a forecaster using multiple causal regression? Multiple Choice Monitoring the economic time series. Identifying the dependent variable. Finding relevant independent variables with the right periodicity and covering the historic period matching the data. Determining the degrees of freedom necessary for the model and making certain they are in line with the demand planning models.

What is generally seen as a strong advantage of the time series forecasting method? a. Economic recessions and competitor actions can cause sales figures to rapidly change b. Dynamic market forces can cause trends to change, which can affect time series forecasts c. Used as a “sanity check” to confirm accuracy of more sophisticated forecasting methods d. Short-term fluctuations (noise) can be present in the raw sales data
