What is the cost of maintenance for a 5-year-old car which ran 100,000 miles as per the quadratic model?

The meteorological department has monthly precipitation data on Lake Mendota for 1 year. A new research assistant wants to calculate a nine-period moving average for the precipitation data. How many observations will she lose in the process?

What is the Variance Inflationary Factor (VIF) of X2?

The meteorological department has monthly precipitation data on Lake Mendota for 1 year. A new research assistant wants to calculate an eleven-period moving average for the precipitation data. How many observations will she lose in the process?

A fourth-order autoregressive model is fitted to a time series with monthly data for 5 years (i.e. sample size n=60). What are the degrees of freedom of the model?

A second-order autoregressive model for annual average mortgage rate is: Rate i = 2 + 1.0(Rate) i-1 – 0.75 (Rate) i-2 If the average mortgage rate in 2023 was 1.35, and in 2022 was 2.0, the forecast for 2025 is

Use the following tables to answer Questions 13-14 A multiple regression was modeled with one dependent variable Y and 4 independent variables X1, X2, X3, and X4. Below are the regression results of the models of Xi with all the other X variables (i = 1, 2, 3, 4):

What is the correct order of autoregressive modeling steps? Test the significance of the autoregressive model with order p (Ap). If the null hypothesis is rejected, this model is selected; if the null hypothesis is NOT rejected, decrease p by 1 and repeat. Test the significance of the autoregressive model with order p (Ap). If the null hypothesis is NOT rejected, this model is selected; if the null hypothesis is rejected, decrease p by 1 and repeat. Form a series of “lagged predictor” variables Yi-1 , Yi-2, … ,Yi-p Use Excel to run regression model using all p variables. Choose p.

What elements of time series data do you observe?
