give an educated guess on a linear regression model for pricing real estate using a real facts date set using numbers and facts. Normally two approaches are used for valuing a real estate property: income and sales comparison. The sales assessment approach values a real estate property based on sale prices of similar properties. In this case the properties with familiar individuality are basically on the same price level‚ it would be typical to use a linear regression model to complete this demonstration

c) Starting with week 5 and ending with week 11‚ forecast registrations using a four-week moving average. [3] d) Plot the original data and the three forecasts on the same graph. Which forecast smoothes the data the most? Which forecast responds to change the best? [4] Problem 2 [4] Given the following data‚ use exponential smoothing (( = 0.3) to develop a demand forecast. Assume the forecast for the initial period is 5. |Period 1 2 3 4 5 6

I expect that there will be a negative relationship between the two variables. In other words‚ as the unemployment rate increases‚ the total number of new
