Consider the following time series. t 1 2 3 4 5 yt 6 11 9 14 15 (a) Choose the correct time series plot. (iii) (i) 14 12 7 Time Ferled (0) 2 Time Period (0) (iv) (II) 14 Time Series Value 10 Time Series Value 10 Time Period [r] 4 2 Time Period R Plot (I) What type of pattern "significantly" exists in the data? (Use 5% level of significance when needed) Randomness & Linear trend (b) Use simple linear regression analysis to find the parameters for the line that minimizes MSE for this time series. If required, round your answers to two decimal places. y-intercept, bo Slope, b MSE= = = (c) What is the forecast for t = 6? If required, round your answer to one decimal place. (d) Use the Holt's method with smoothing constants of 0.5 for alpha and 0.9 for gamma. Find the equation of the forecast line and the MSE for this method. If required, round your answers to two decimal places. y-intercept, bo Slope, b MSE= = (e) What is the forecast for period 10? Do not round your interim computations and round your final answer to two decimal places. (f) Which of the two methods perform better? Regression 52F Mectly coor Q Harry Houdini's...
