The time series regression model contains a variable W and a regression equation of y = 80 + 5W + 2w2 to forecast future values. If W represents a time period, what is the forecast for time period 2 and the forecast error if the actual value for time period 2 is 100? Select the best answer. forecast value = 98; forecast error is 2 forecast value = 90; forecast error is 10 forecast value = 98; forecast error is-2 forecast value = 100; forecast error is 0
