Extracted text: Consider the following time series data. Week 1 2 3 4 Value 19 13 16 12 18 14 Using the naive method (most recent value) as the forecast for the next week, compute the following measures of forecast accuracy. Round the intermediate calculations to two decimal places. a. Mean absolute error (to 1 decimal). b. Mean squared error (to 1 decimal). c. Mean absolute percentage error (to 2 decimals). % d. What is the forecast for week 7 (to the nearest whole number)?
