Likelihood ratio test for restrictions on alpha
阿尔法限制似然比检验
译者:生物统计家园网 机器人LoveR
描述----------Description----------
This function estimates a restricted VAR, where the restrictions are base upon \bold{α}, i.e. the loading vectors. The test statistic is distributed as χ^2 with r(p-m) degrees of freedom, with m equal to the columns of the restricting matrix \bold{A}.
此功能估计受限制的VAR,这里的限制是立足\bold{α},即加载向量。检验统计量的分布χ^2r(p-m)自由度,m等于列的限制矩阵\bold{A}。
用法----------Usage----------
alrtest(z, A, r)
参数----------Arguments----------
参数:z
An object of class ca.jo.
对象的类ca.jo。
参数:A
The (p \times m) matrix containing the restrictions on \bold{α}.
(p \times m)基质中含有的限制\bold{α}。
参数:r
The count of cointegration relationships; <br> inferred from summary(ca.jo-object).
计数的协整关系;参考推断summary(ca.jo-object)。
Details
详细信息----------Details----------
The orthogonal matrix to \bold{A} can be accessed as object@B. The restricted \bold{α} matrix is normalised with respect to the first variable.
正交矩阵\bold{A}也可以访问object@B。受限制的\bold{α}矩阵被归一相对于第一可变。
值----------Value----------
An object of class cajo.test.
对象的类cajo.test。
