A Modified Spatiotemporal Mixed-Effects Model for Interpolating Missing Values in Spatiotemporal Observation Data Series

Table 2

The RMS values of residuals of interpolated results for missing data with 139 stations (unit: mm).

Station no.	MSTME	KKF	STME	Improvement 1 (%)	Improvement 2 (%)
1	12.0	14.6	14.8	17.8	18.9
2	8.8	17.6	21.1	50.0	58.3
3	8.7	20.7	14.1	58.0	38.3
4	15.4	25.6	19.9	39.8	22.6
5	7.0	13.6	32.7	48.5	78.6
6	15.9	40.9	76.8	61.1	79.3
7	17.3	21.2	33.9	18.4	49.0
8	18.1	37.5	33.2	51.7	45.5
9	20.1	26.4	51.3	23.9	60.8
Average	13.7	24.2	33.1	43.4	58.6

The “Improvement 1” is the improvement rate of the MSTME model over KKF model, and the “Improvement 2” is the improvement rate of the MSTME model over STME model.
