> It seems variance and standard deviation stream evaluators are not supported
> by any of the solr version. For example,
> let(echo="m,v,sd", arr=array(1,3,3), m=mean(a), v=var(a),
> sd=stddev(a))
> So far, only the mean function is implemented. I think it is useful to have
> var and sttdev functions separately as a stream evaluator.
