is anyone aware of any GOOD statistics packs/libraries in c++?
If possible, I would need them to be QUICK, as I have a lot of data, and don't want generation of the statistics to be TOO long. And of course, I would like it to be reliable, i.e. to produce reliable information.
The statistics I need to produce, at least, are:
Sum of values
Count of values (how many are there)
Largest (n), i.e. n-th largest value
smallest (n), i.e. n-th smallest value
Confidence Level for any % value
If anyone has ANY suggestions, that would be awesome!
Yep, I haven't used it much, so far, myself, either. I have been able to do most of the stuff I have needed, so far, in Excel, or, other Spreadsheet programs, and, I found it A LOT more straight-forward, for what I wanted to do.
But, If, I can use R, basically, programmatically, from within code (in this case, C++), that Does seem like a lot of stuff that can be done "at once", since R seems to be an ok statistics "pack". Again, however, I am not sure, yet, how to use R from C++.
I have found some information. There is some stuff, called "Rcpp", but, from what I can tell, it seems to have a lot of configuration required, and, I was hoping there would be something more straight-forward.
Again, If ANYONE has ANY info on using R, from within C++, or other programming idioms, I am glad for any pointers, or additional help.
Also, if anyone has any info about other "statistics" packs, I am also happy to have that Information!
Doesn't any of the packages mentioned in the stackoverflow topic you linked suit you? I think implementing yourself is not a good idea - it will just take a lot of time and you need a lot of tests to make sure it's correct.
well, I don't like the ideas at stackoverflow that much, as they usually are fairly complicated. I have already started with creating my own implementation, and, at least for the functions I am needing, I THINK I should be able to manage the testing!
However, if anyone has any future suggestions, I would still be very interested in that!
