Correcting Air-Pressure Data Collected by MEMS Sensors in Smartphones

Table 5

Results of the linear-regression analyses for air pressure exclusively and results that include temperature and humidity, along with air pressure, at public weather stations.

Results of analysis	Only air pressure	Air pressure plus temperature and humidity	Mean of public weather stations (air pressure, temperature, and humidity)
MAE	1.64	1.41	0.78
RMSE	2.12	1.86	1.57
TN	930,883	532,946	528,740

MAE: mean absolute error, RMSE: root mean square error, and TN: total number of instances.
