I have a set of data which I used linear regression to get a function for. I have done it by hand and followed a tut (http://reference.wolfram.com/mathematica/LinearRegression/tutorial/LinearRegression.html).
In the tut it says that it plots dotted lines with 95% confidence interval. This interval does not match my hand-calculated one. I can not seem to find where exactly the CI is defined to 95%?
Thanks in advance for the help! :D
