Table 1.

Balanced accuracy (BA), true positive (TP) and true negative (TN) rates for the nonparametric switching AR model trained on walking and balance tests performed in a controlled environment. The TP rate reflects the ability to correctly identify an activity when occurring, and the TN rate reflects the ability to correctly indicate the lack of that activity whenever it is not occurring.

Behavior	BA	TP	TN
Walking	95%	96%	93%
Standing up straight	95%	98%	91%
Phone stationary	98%	100%	95%
Sustained phonation	98%	99%	97%
