KINDLY show in detail your work and hopefully to answer all of
the question
Question 1. Consider the following tine series data Week Value 1 18 2 13 3 16 4 11 5 17 6 14 a) Construct a time series plot. What type of trend exists in the data? b) Develop the three-week moving average forecasts for this time series: = =-- a;Xt–j, where a; = , j = 1,2,3, zero else. Compute the mean squared error. Compute a forecast for week 7. c) Develop the three-week moving average forecasts for this time series: = 2 --- a;Xt–j, where (az, az, az) = (3, 2, 1), zero else. Compute the mean squared error. Compute a forecast for week 7. d) Use a = 0.2 to compute the exponential smoothing forecasts for the time series. Compute the mean squared error. Compute a forecast for week 7. e) For the above data calculate BXq, B2X4, VX4, V2Xt, and 72X4. f) For the above data calculate y(h), and p(h).
