I'm not sure I understand. You have financial data and want to throw away some outliers?? Why would you ever do this?
First of all, I'd suggest you pay close attention to what the data is trying to say. Maybe your distribution is not normal after all (see tests for normality etc). Maybe you shouldn't force your normality assumption upon the data. -----Original Message----- From: Melanie Vida [mailto:[EMAIL PROTECTED] Sent: Friday, February 25, 2005 1:30 PM To: r-help Subject: [R] Temporal Analysis of variable x; How to select the outlier threshold in R? For a financial data set with large variance, I'm trying to find the outlier threshold of one variable "x" over a two year period. I qqplot(x2001, x2002) and found a normal distribution. The latter part of the normal distribution did not look linear though. Is there a suitable method in R to find the outlier threshold of this variable from 2001 and 2002 in R? ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
