In time series data, linear regression allows to incorporate in the model... (a) a linear time trend (b) an exponential time trend (c) a quadratic time trend (d) all of the previous
You have fitr a simple regression model to monthly time series data nad the model is Y1 = 1.2 + 0.5^t. What is the interpretation of 0.5, the coefficient associated with t?
The model that assumes that the actual time series value Yt is the product of a trend-cycle, season, and error component is additive Holt-Winters model weighted moving average model linear trend regression model Holt linear trend model purely additive time series model purely multiplicative time series model
What are the major elements in applying Time Series Regression Model to forecasting? Could you provide us with a real-world example that you may use this method in forecasting? Also, please choose one of the models that would be most appropriate for your case and explain your rational.
Q3. [10 points [Serial Correlation Consider a simple linear regression model with time series data: Suppose the error ut is strictly exogenous. That is Moreover, the error term follows an AR(1) serial correlation model. That where et are uncorrelated, and have a zero mean and constant variance a. 2 points Will the OLS estimator of P be unbiased? Why or why not? b. [3 points Will the conventional estimator of the variance of the OLS estimator be unbiased? Why or...
Which of the following is NOT a time-series model? a. exponential smoothing b. naive approach c. multiple regression d. moving average
what are the problems that autocorrelation created when using OLS regression in time series data.
time series 3. Specify and interpret the model in terms of a time- series data Xt for the following multiplicative models ARIMA: (1, 0, 0)(1, 0, 0)4 ARIMA (0, 1, 0)(1, 1, 0)6 ARIMA (0, 1, 1)(0, 0, 1)12
Time series analysis: is not appropriate for forecasting. is a regression where the independent variable is units of time. is a practical application of multiple regression. All of the above are true.
