That feels of "I miss nanstd" from MATLAB, I know it bro.
```
Pkg.add("nanstats")
Using NanStats
```
- nanmedian : computes the median, even if there are nans in your array!
- nanmean : computes the mean, even if there are nans in your array!
- nanstd : computes the standard deviation.... yep, you get it.
- nanste : computes the standard error.... despite nan's!
- nansum : a sum, with nans!
- nancumsum : cumulatively sum up that vector, even if there are nans.
