percentile access

Having access to percentile computations (for SFrame columns and SArrays) would be extremely helpful - especially when doing outlier trimming (which would be yet another feature request).

Hi @borowcm,

What exactly do you mean by percentile computations?

Currently we can calculate quantiles https://dato.com/products/create/docs/generated/graphlab.Sketch.quantile.html#graphlab.Sketch.quantile, which can be used to calculate the value for a particular percentile.

Hi @piotr sorry, That construct was missing from https://dato.com/learn/translator/ - I was orignally looking for a SFrame column-based function like .mean() .max(), for percentiles/quartiles (similar to those provided in numpy ) but if using a Sketch object is the only way (and recommended way) to access column-wise SFrame statistics such as Quartiles/Percentiles then I can do that.

@borowcm,

This brings up a good point, we may want to think about how this functionality is accessed and update the translator.

Thanks for the thoughts!

Cheers! -Piotr
