1,2,3,4,5,6,7,8,9,10 This will give you several options for the type ofcurve-fitting you want to do. I have a question: when I implement your solution I get the answer you provided where the slope for Lif Exp as a function of Cig is -0.83705. If lab = TRUE (default FALSE), then an extra column is appended to the output from TRegCoeff containing the labels “intercept” and “slope”. You can analyze residuals just as you do for OLS. I have not yet received the file. It turns out that this is equivalent to minimizing: The value of b that minimizes this expression is given by. Then I started plugging in my own data and it’s doing something weird.

The intercept regression coefficient is then given by. In Excel, an Array Formula allows you to do powerful calculations on one or more value sets. I don’t understand why it’s like this. In the previous two Excel tutorials, we have discovered two ways to obtain least-squares estimates of the slope and intercept of a best-fit line: use the slope() and intercept() functions; add a trendline to a scatterplot I just sent the email again to both of your email addresses. Are you able to get a result of -1.19467 for the beta when the inputs are switched, I cannot. Using least squares regression output. The MSE now is about 14 million – 14,138,888 to be exacti. and thx so much, for the great help im getting because of your awesome work with this website.
