DATA QUALITY ANALYSIS OF HONGSHAN GEOMAGNETIC STATION USING STEPWISE REGRESSION ANALYSIS
-
摘要: 选用逐步回归分析方法,利用红山地磁台2009年观测数据的基线值数据,计算台站地磁观测系统的温度系数与滑动系数以及年剩余均方差,通过这3个指标的结果,给出观测系统受这3个参数影响的程度,为控制红山台地磁观测数据的质量提供依据。同时,对台站合理的选用基线值提供有力帮助。Abstract: Using stepwise regression analysis methods and baseline value data at Hongshan geomagnetic station, this paper calculates temperature coefficient, sliding coefficient and annual residual mean square deviation of the geomagnetic observation system to study the influence degree of the three coefficients, provide evidence for data quality controlling at Hongshan geomagnetic station and provide help for reasonable selection of baseline value.
