Filtering outliers in linear data

[Ducc]

Hey,

I have some data that should be roughly linear. There is the chance for outliers in the data, and I want to remove as many as possible. From my readings in statistics (of which I am largely ignorant), 2-d data filtering is really a function of the data itself; in other words, it's hard to filter the data if you don't know what it looks like. However, since my data is linear, I see no reason a generic filter wouldn't work.

1. Is there a place where I can find filtering VI's for linear data, available for free?

2. If not, are there techniques you can recommend to write my own?

Thanks!

I would also like to know where to get a "standard deviation of the mean" VI. There seems to be so much missing from the Student Version of Labview 7.0. Maybe I just can't find it?
