摘要
本文用多参数统计定值的新模式进行标样定值。对离群值的处理提出了新方案。采用11种统计参数对原始数据进行处理,并将这11种参数的算术平均值、中位值、几何平均值、选择平均值、Hampel M估计值和主族众数的平均值作为最佳定值。在NCR TOWER-1632多用户高档微机UNIX操作系统下开发了多参数模式定值软件MPDPS,对6个新研制的标样进行了定值。
A software system MPDPS, dedicated to NCR TOWER-1632 computer, was devised which allows the data from collaborative laboratories to be processed to obtain arithmetic mean, geometric mean, preferance mean, median, trimean, 25% trimmed mean, Gastwirth median, mode, modian, dominant cluster mode and Hampel M-estimate. All the estimators are again processed to obtain arithmetic mean, geometric mean, preferance mean, median, dominant cluster mode and Hampel M-estimate, and their arithmetic mean is assigned for the certificate value for an element. Composition values of six newly-prepared geochemical RMs (GSR 7-12) were derived by this multiparameter data processing model.
