If you are calculating the value of y, the intercept shows at which point the line crosses the y-axis. On the other hand, the absolute value of the observed t-value for the a0 constant term is 2.
It ranges from 0 to 1 and the closer to 1 the better the fit. First, provide what is called a point estimate. Figure 6 When array-entered in 5 rows D2: First, it helps if you have a visual representation of the linear equation you are trying to write down.
Features Of This Template 1. Extrapolating five years of data this far out into the future is simply dangerous. The section Understanding the result addresses how these errors help determine if the coefficients are significant.
Confidence Intervals Among the uses of a regression is the ability to estimate missing information as well as information outside of the range of data analyzed.
K3 contain the formulas shown below. Since it is less than the critical t-value, we conclude that, statistically speaking, the constant is zero. For example, in the example used in the beginning of this chapter, we modeled the sales volume as a linear function of the month.
Figure 10 Next, we calculate the predicted value and the confidence interval values for the months 1 through Will I make lots of mistakes? Then, link each image to that particular project file. Just click on the following link: The F statistic, or the observed F-value, is a measure of the significance of the regression as a whole.

For reasons that will soon be apparent, we start with the last row. Keep in mind that n-k is also the df value in row 4 of the result.
Among others, there were seasonal trends, annual trends, day-of-week patterns, storm-related surges in call volume, etc. If one is unlucky, the result may lead to bad organizational or individual decisions.
