Possibility to avoid certain values which are way too deviant while calculating threshold

[Rahul Amaram]

Hi,

I had a quick question. Let us say we calculate the threshold based on 
the values of the past six days, one value per day. Now let us say, out 
of 6 values, one of these values is way too deviant. Then is it possible 
to exclude this deviant value from calculating the threshold?

Thanks,
Rahul.
