Hi,
I am trying to restrict a data set so as not to included outliers.
Specifically, I would like to specify a percentage where a fraction of
observations are eliminated from the data set, much in the same way that the
trimmed mean function works - but leaving the restricted data set intact.
I have been using a function which will restrict the data set using:
> trim=function(x,p){
> o=order(x)
> xo=x[o]
> n=length(xo)
> tl=round(n*p)
> print(xo[(tl+1):(n-tl)])}
However I was wondering if anyone knew a more elegant and simple method to get
the same result.
Thanks in advance.
