I analyzed the sensor Liberty School (db5d6b3b79f5830e_39237) in the Methow Valley during September 2020. Despite being a well-functiong sensor based on other plots, PurpleAirSoH_dailyABtTest() reveals that 25 days out of 30 have significant p-values indicating that the sensor didn't function well. The same issue is true for other sensors including those that actually did not function well according to other plots (e.g. Willowbrook_Farm, f96deab8c29aa42b_10134).
PurpleAirSoH_dailyABtTest() seems not to be helpful in evaluating the functioning of the sensors since it does not discriminate well-functioning sensors from poor-functioning ones.
