Taylor于2001年首先提出主要用来比较几个气象模式模拟的能力因此该表示方法在气象领域使用最多但是在其他自然科学领域也有一定的应用。 泰勒图常用于评价模型的精度常用的精度指标有相关系数correlation coefficient标准差standard deviation以及中心均方根误差centered root-mean-square, RMSE。 一般而言泰勒图中的散点代表模型辐射线代表相关系数横纵轴代表标准差而虚线代表均方根误差。泰勒图一改以往用散点图这种只能呈现两个指标来表示模型精度的情况。 泰勒图分为标准化泰勒图和未标准化泰勒图用的比较多的是标准化泰勒图。标准化泰勒图即对参考值与变量值的标准差与均方根误差同除以参考值的标准差令参考值1E0并消除其物理量单位。 泰勒图基本介绍 1 绘制包下载 安装网站Taylor Diagram Google Code Archive 此外还需要allstats和ptable函数下载链接分别如下 Github-allstats.m函数 % STATM Compute statistics from 2 series % % STATM allstats(Cr,Cf) % % Compute statistics from 2 series considering Cr as the reference. % % Inputs: % Cr and Cf are of same length and uni-dimensional.
