摘要
利用少数具有频率特性的点据分析其统计规律需进行线型拟合,针对点据少、频率标准不确定的特点可采取拟合统计参数法。统计参数拟合方法可利用离差平方和最小准则或相对离差平方和最小准则。通过拟合确定的统计参数可广泛应用于分析已有资料的合理性,内插其他不同频率标准的设计值等,具有精度高、应用方便、理论基础可靠等特点。
It is necessary to draw appropriate line type for analyzing statistic s parameters with limited frequency data.It is possible to estimate statistics p arameters with limited uncertain frequency data.The rules include the minimum of sum square variation or the minimum of sum relative square variation.The method can be widely used to analyze the rationality of existing data or to calculate the value of other standard frequency with characteristics of high accuracy,appl ication of convenience and reliable theoretical foundation.
