Hi,
In the help for spectrum it says:
" If available, a confidence interval will be plotted by
'plot.spec': this is asymmetric, and the width of the centre mark
indicates the equivalent bandwidth. "
What you get is a blue bar on the right side of the plot.
I can understand the width of the centre mark.
But how does one make use of or interpret the bar itself?
What I would like to do is draw confidence curves on either side of the
periodogram.
Is this possible or reasonable?
