Monica works at a regional weather office on the Atlantic coast. She notes (from the office records) that hurricanes have

made landfall on the coast somewhere near their city of Johnstown in the past 11 years. Monica notes that forecasted

landfall has been different from actual observed landfall as shown in the table below.

How accurate has the forecast been? Do you think this difference matters to a beach town? Can you develop a forecasting

system model that may be more accurate?

Explain your methodology and ideas in a paper of at least four pages. Be sure to research sources to support your ideas,

Introduction
I want to predict the miles from Johnstown for future years. The data for actual miles from John town for 11 yearsÂ is given below. I consider predictions based on methods of linear regression, moving average, and exponential smoothing.Â The best method is select on basis of Mean absolute deviation (MAD) and mean square e
or (MSE).

Linear regression is given in the form of Y-hat = b0 + b1*X.Â beta_0 and Beta 1 are intercept and slope of the regression equation respectively. In this case, the regression equation is y = 9.945 + 0.19*x.Â my dependent variable (y) is miles from Johnstown. The independent variable (x) is the year. The predictions for 11 years on the basis of linear regression or trend analysis is given in the table below. Fox, J. (1997).Â
