existing adaptive methods and constant parameter methods when the estimation and evaluation samples both contain a level shift or both contain an outlier. An empirical study‚ using the monthly time series from the M3Competition‚ gave encouraging results for the new approach. Keywords: Adaptive exponential smoothing; Smooth transition; Level shifts; Outliers INTRODUCTION Exponential smoothing is a simple and pragmatic approach to forecasting‚ whereby the forecast is constructed from an exponentially

Finally‚ it was measured the association between two variables (correlation coefficient) to understand the relationship between more than one variable. Four variables were examined‚ and the results are described as follows: a.

conventional= 5631695 + 4.74 wind. There was 23 cases used and 28 cases contain missing values and we got a p value of .183. We achieved a r-squared of 8.3% which is far too low‚ so we knew that we had to take out outliers in order to get a high R-squared. Washington was a large outlier because they have a large number of hydroelectric plants‚ so we took Washington out of our data. This gave us a regression equation of hydroelectric conventional = 2996890 + 4.41wind. There were 22 cases used now

you can see that Dick’s salary is an outlier compared to the mean. b) The median of these seven salaries is $23‚500. I got the median by first putting the numbers in order. Since it is an odd amount of numbers‚ I just find the center of the data after they were in order. This value does not really compare to all of the individual salaries; it has no relation other then it is just in the center. Dick’s salary does not compare to the median because it is the outlier‚ but mostly everyone else’s does because
