VC++环境下的数据误差分析

Data Error Analysis under VC++

VC++环境下的数据误差分析程序具有测量数据均值计算、残余误差图绘制、系统误差和粗大误差分析等功能。该程序与系统测试软件兼容,在CERRORDoc中用链表存放数据,定义数组。采用残余误差观察法观察残差图中各个残余误差大小和符号变化规律,可直接判断有无系统误差。使用残余误差校核法,若测量列中前K个残余误差之和与后(n -K)个残余误差之和不相等,则测量列存在线性系统误差。

Data error analysis program under VC++ and Win 2000 has functions of calculating equalizing value of tested data, drawing chart of residual error, system error analysis and rough error analysis. The program is compatible with testing software, data is saved and arrayis defined with chain table in CERROR Doc. Big and small of residual error and rule of sign change was observed with inspection method of residual error, and if it had system error or rough error and so on was identified. Check method of residual error was used to judge data error, as if sum of front K residual error was unlikeness with sum of back n-K residual error in measure row, it shown that exist linear system error in measure row.
