Q3. Let the given data set be as follows Time GDP (In crore) 2020 2 2021 5 2022 Based on the above information, answer the following questions. i. ii. Fit the regression model by using the matrix method as GDP, a+pGDP +& Find the estimated error term. Forecast the GDP for the year 2023. ソーダ 12

Refer to the quarterly value of Gross Domestic Product (GDP in billions of current dollars) in China from 2021q1 to 2023q4. You are going to analyze GDP by an additive model with a trend component (Tt) and a seasonal component (St), and forecast GDP using the seasonal decomposition method. Year Quarter t GDP (Y₁) CM(4) Detrended 2021 1 1 24920 2 2 28284.9 3 3 29128.8 ? ? 4 4 32589.9 ? ? 2022 1 5 27034.4 ? ? 2 6 29244.7 ? ? 3 7 30794.2 ? ? 4 8 33399.1 ? ? 2023 1 9 28442.3 ? ? 2 10 30829.3 ? ? 3 11 31997.6 4 12 34789 a. Use an CM(t|4) [centered moving average of order 4] series to estimate the GDP series from t = 3 to 10. b. Calculate the seasonal factors for each quarter with a zero mean, by first obtaining the detrended revenue series from t = 3 to 10. c. In this seasonal decomposition method, why is it necessary to use moving averages to process time series data first? How about using moving average of order 5?

Gross Domestic Product The following table givesthe gross domestic product (the value of all goodsand services, in billions of dollars) of the UnitedStates for selected years from 2000 to 2018.a. Create a scatter plot of the data, with y representing the GDP in billions of dollars and x representing the number of years after 2000.b. Find the linear function that best fits the data, withx equal to the number of years after 2000. Reportthe model with three significant digits.c. Graph the model with the scatter plot to see if theline is an excellent fit for the data.

Gross domestic product per capita is the ratio of total gross domestic product to population.gross domestic product, a unit of timemonetary value of the final goods and services produced in the economy (let be in TL) and population, unitaccording to the number of people in that economy at the time,a) write down the unit of measure and size of the gross domestic product variable per capita. b) what is the relationship between gross domestic product per capita, total gross domestic product and population growth?Express your conclusions in a sentence by making inference
