吻合度检验模型

 

(1) 评估者的吻合度:

 

式中, y是观测值;是模型的输出值; 表示第个观测值;a表示第a个状态变量。

 

(2) 作为吻合度的加权最小平方数:

 

 

另外的一个特殊情况是通过变量加权并且权重独立于即:,其吻合度标准的可能性函数可表达为:

 

式中, 是参数的期望值;是另外的已知或未知的参数;是已知时, 的概率密度。

 

(3) Theil不等式系数:

 

 

 

 

 

式中, n是样本点数。此指数考虑到了平均值中的差异,标准差中的差异以及预测数据和观测数据之间的不完全共变。

(4) 另一个标准类似于统计:

 

 

(5) 当状态变量和输出变量都能与观测值相比较时,则下面的误差函数,它也是一个加权最小平方数,能够被用来检验吻合度:

 

式中,均为向量;QR是非负加权系数。
