Compute link values from real parameters
从实际的参数计算链接值
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Computes link values from reals using 1-1 real to beta(=link) transformation. Also, creates a v-c matrix for the link values if vcv.real is specified.
计算实数,使用1-1真实的测试(链接)转换的链接值。此外,创建一个VC矩阵的链接值,如果指定vcv.real。
用法----------Usage----------
compute.links.from.reals(x, model, parm.indices = NULL,
vcv.real = NULL, use.mlogits = TRUE)
参数----------Arguments----------
参数:x
vector of real estimates to be converted to link values
要转换为链接值的实际估计矢量
参数:model
MARK model object used only to obtain model structure/links etc. If function is being called for model averaged estimates, then amy model in the model list used to construct the estimates is sufficient
MARK模型对象仅用于获取模型结构/链接等如果函数被调用模型平均估计,然后艾米模型的构建估计在型号列表中是足够的
参数:parm.indices
index numbers from PIMS for rows in design matrix(non-simplified indices); x[parm.indices] are computed
索引号从PIMS设计矩阵中的行(非简单的指标);计算X [parm.indices]
参数:vcv.real
v-c matrix for the real parameters
V-C矩阵的实际参数
参数:use.mlogits
logical; if FALSE then parameters with mlogit links are transformed with logit rather than mlogit for creating confidence intervals for each value
逻辑,如果罗吉特而不是mlogit的转化为创建的每个值的置信区间为FALSE,则参数与mlogit链接
Details
详细信息----------Details----------
It has 2 uses both related to model averaged estimates. Firstly, it is used to transform model averaged estimates so the normal confidence interval can be constructed on the link values and then back-transformed to real space. The second function is to enable parametric bootstrapping in which the error distbution is assumed to be multivariate normal for the link values. From a single model, the link values are easily constructed from the betas and design matrix so this function is not needed. But for model averaging there is no equivalent because the real parameters are averaged over a variety of models with the same real parameter structure but differing design structures. This function allows for link values and their var-cov matrix to be created from the model averaged real estimates.
它有2个同时使用相关的模型平均估计。首先,它是用来变换模型所以正常的置信区间可以构造上的链接值,然后再转化为实际空间中的平均估计。第二个功能是,使该错误distbution被假定为多元常态为链接值的参数的自举。从一个单一的模式,很容易链接值的测试版和设计矩阵的构造,所以这个功能是不需要的。但是,对于模型的平均是不相等的,因为真正的参数的平均值多种型号相同的参数结构,但不同的设计结构。此功能允许链接值和它们的变种冠状病毒的矩阵,可以从模型中创建的平均实际的估计。
值----------Value----------
A list with the estimates (link values) and the links that were used. If vcv.real = TRUE, then the v-c matrix of the links is also returned.
一个列表的估计(链接)和链接,使用。如果vcv.real = TRUE,则VC矩阵的链接也回来了。
