Given that we offer exponential weighted average and std, and rolling count, avg, and std for update_by(), I think it's reasonable to support cum_count(), cum_avg(), and cum_std(). These are natural things to want to compute, and I'm having a tough time computing them by composing existing operations.
Here is the gap in cumulative/rolling operations compared to Numerics.java array operations:
count (cumulative, rolling already exists)
avg (cumulative, rolling already exists)
count_neg, count_pos, count_zero (can implement using modification to CumSpec)
abs_avg
std (cumulative, rolling already exists)
wstd
var
wvar
cov
cor
ste
wste
tstat
wtstat
median
percentile
