Multiple linear regression equation between LST and brightness temperatures of AVHRR channels 4 and 5 was almost at the significant level (p＜0.05), and the level was not improved by adding brightness temperature of AVHRR channel 3 as a regressor. Path analysis is a statistical technique that partitions correlations into direct and indirect effects, and differentiates between correlation and causation. The results of path analysis showed that the direct effects and indirect effects of brightness temperatures of AVHRR channels 4 and 5 to LST were strong, respectively, the direct effect and indirect effects of brightness temperature of AVHRR channels 3 to LST were weak. These implied the brightness temperatures AVHRR channels 4 and 5 should be involved in retrieving LST.

多元线性回归分析结果表明，土地表面温度与AVHRR第4、5波段亮度温度间的回归方程接近5％的显著水平；通径分析的结果表明，AVHRR第4、5波段的亮度温度对土地表面温度的直接作用和间接作用均较强，而AVHRR第3波段的亮度温度对土地表面温度的直接作用和间接作用均较弱，因此，在反演土地表面温度时必须同时考虑AVHRR第4、5波段的亮度温度。

Hierarchical linear modeling is the most frequently used technique for analyzing multilevel data. In this paper, the twelve key issues in multilevel research and/or using HLM software were reviewed, and provided their exact meanings and feasible solutions. The 12 key issues included intraclass correlation coefficient, sample sizes, formation of organizational constructs, centering problems, fixed effect and random effect, estimation methods, goodness of fit index, explained variation, multicollinearity, robust standard error, level one variance equation, and empirical Bayes estimates.
