A simple, easy to use and efficient Arduino library to compute running statistics.
It can compute the running mean, variance and standard deviation. If you need any other statistics, open an Issue and I can look into adding it to the library.
Install RunningStats from the library manager.
Specify RunningStats as lib_deps in platformio.ini
lib_deps = RunningStats
Or simply add it to your project through the library interface in PlatformIO.
Include the library using:
#include <RunningStats.h>
Start an instance of the library using:
RunningStats stats;
Then, simply call the function update() with your float value, each time you want to update the running statistics:
stats.update(x); // where x is a float value
To get the computed statistics, you can call at any time the following functions:
stats.mean(); // return the computed running mean
stats.std(); // return the computed running standard deviation
stats.variance(); // return the computed running variance
To reset the running statistics counts to zero, you can call the reset() function:
stats.reset();
