What is the forecast for period 16? Compute the initial trend estimate (T+) for Period 5 as follows: (Period 4 data - Period 1 data) / 3. Then compute the initial trend-adjusted forecast (TAF+) for Period 5 as follows: Period 4 data + Initial trend estimate for Period 5. Then compute all remaining values (including the St value for Period 5) using the textbook formulas or Excel template. (Round the "Trend"values (Tt) to 3 decimal places and all other intermediate forecast values (TAFt and St) to 2 decimal places. Round your final answer to 2 decimal places.) Forecast for period 16 Problem 3-10 After plotting demand for four periods, an emergency room manager has concluded that a trend-adjusted exponential smoothing model is appropriate to predict future demand. The initial estimate of trend is based on the net change of 19 for the three periods from 1 to 4, for an average of +6.33 units.
