...lly plot
confidence intervals , instead of standard error.
I understand I have to use the ci.fun option, but I'm not quite sure
how.
Like this :
> qt(0.975,df=n-1)*s/sqrt(n)
but how can I apply it to visualize the length of the student's T
confidence intervals rather than the stdandard error of the plotted
means ?
