I think the authors might have had their reasons for leaving it out. There have been quite a few threads ofver the years discussing why it is not a straightforward task to define a confidence interval. Do you have a particular approach that is acceptable in your domain of investigation?
Hello. How can I plot the regression curve with its confidence interval? I use nls(y~a*x^b), then plot(x,y), add curve with lines(x,predict(nls(y~a*x^b))). But I can't add to plot CI for my curve.
