- When a forecaster uses the ______________ method, she or he assumes that the time series components are changing slowly over time.Explain the various concepts & tools of regression with time series data?How do I construct a time series plot and determine pattern of data? What formula do I use for regression analysis to find the parameters for the line that minimizes MSE for this time series?
- Two forecasting methods have been used to evaluate the same economic time series. The results are given Compare the effectiveness of these methods by computing the MSE, the MAD, and the MAPE. Do each of the measures of forecasting accuracy indicate that the same forecasting technique is best? If not, why?What is the seasonality in time series data? How do you control seasonality in time series regression model. Please provide an example.Which of the following time series forecasting methods would not be used to forecast seasonal data?
