Hello,
what are they meaning? It could be something that
would show a threshhold above which the result is
indicating different meanings then just random noise.
But there is no description on the definition of those lines,
so it means nothing, if it is not clearly defined.
Where can I find a detailed definiton?
Ciao,
Oliver
Look at
?plot.acf
for which there is a pointer on the help to acf:
'The generic function plot has a method for objects of class "acf". '
Note that if you can't guess what the lines are on the acf plot you don't
know enough about time series to be using an acf plot and had best get a
book on time series and read it. Any standard reference on time series
should explain it, for example Chatfield: The Analysis of Time Series.
