Boxplot

Dear,

I have to winsorize my data. Since it isn't possible to do this directly in Eviews, I thought about looking at a Boxplot and then changing the data myself.
Using Eviews7, how do I know if the boxplot is set on a 5-95% interval? And how can I changes the values displayed on the axes? I need to know exact values of the data,and my boxplot just gives me the values 2-4-6-8-10.

Thanks in advance!

Just download the Trim add-in. It performs Winsorising.

Unfortunately I cannot download this program on the computers of my university...
Is it possible to do it my way?

I don't think you'll be able to do it via a boxplot. You could, of course, use the @quantile function to tell you what the 0.05 and 0.95 quantiles of the series are.

For example,

Code: Select all

series ytrim = @recode(y>@quantile(y, .95), na, y) ytrim = @recode(ytrim<@quantile(y, .05), na, ytrim)
