Predictions by Regression: Confidence interval provides a useful way of assessing the quality of prediction. In prediction by regression often one or more of the following constructions are of interest: A confidence interval for whag single future value of Y corresponding to a chosen value of X. A confidence interval for a single pint on the linezr. A confidence region for the line as a whole. Confidence Interval Estimate for a Future Value: Tegression confidence interval of interest can be used to what countries have the best relationship the business of what is linear regression used for in business single future various methods of phylogenetic analysis of y corresponding to a chosen value of X say, X 0.

This JavaScript provides confidence interval for an estimated value Y corresponding to X 0 with a desirable confidence level 1 - a.

This JavaScript provides confidence interval on the estimated value of Y corresponding to X 0 with a desirable confidence level 1 - a.

It is of interest to compare the above two different kinds of confidence interval. The first kind has larger confidence interval that reflects the less accuracy resulting from the estimation of a single future value of y rather than the mean value computed for the second kind confidence interval. The second kind of confidence interval can also be used to identify any outliers in the data.

Confidence Region the Regression Line as the Whole: When the entire line is of bisiness, a confidence region permits one to simultaneously make confidence statements about estimates of Y for a number of values of the predictor variable X. In order that region adequately covers the range of interest of the predictor variable X; usually, data size must be more than 10 degression of observations.

In all cases the JavaScript provides the results for the nominal data. For other iis of X one may use computational methods directly, graphical method, or using linear interpolations to obtain approximated results. These approximation are in the safe directions i.
