COnfidence Intervals in Multiple Regression
How do I calculate the confidence interval for each year's forecast with the output Excel gives me regarding the confidence intervals? I ran a multiple regression in Excel using the Analysis Tool Pack and I can see the upper and lower limits, but I do not know how to use those numbers to calculate the interval for each forecasted period.
When preforming a regression analysis, it gives us two confidence interval. The first one if for Beta1, what is the second for?
it seems like this should be simple, but I can't figure it out.how can I develop (and chart) 95% confidence interval lines around a trend line in a regression scatter plot? The regression summary output table includes values for the lower and upper 95%, but I can't figure out how to make use of this information. And the stuff in Help on the CONFIDENCE() function is no help at all.
I am trying to create a bar chart (or line graph) with confidence intervals.
I need to make a graph that shows four means w/ associated confidence intervals and I have no idea how to do so. Any advice would be much appreciated.
