title: Difference between RunningAverageRssiFilter, ArmaRssiFilter, Kalman filter in Altbeacon SDK
body: <p>I understand that we can have different implementations for RssiFilter using setRssiFilterImplClass in Altbeacon SDK.  I tried out all above filters (RunningAverageRssiFilter, ArmaRssiFilter, Kalman filter) and i found that there is not much difference in distances which i got. So what is the exact difference and what is the use case where in i have to select one of these filters.</p>
