描述----------Description----------

The most pertinent matrices and other quantities pertaining to a QRR-VGLM (CQO model).
最相关的矩阵和其他有关的一个QRR VGLM(CQO模型)的数量。


类对象----------Objects from the Class----------

Objects can be created by calls of the form Coef(object, ...) where object is an object of class "qrrvglm" (created by cqo).
对象可以通过检测的形式Coef(object, ...)其中object是类的一个对象"qrrvglm"(创建cqo)。

In this document, R is the rank, M is the number of linear predictors and n is the number of observations.
在这份文件中,R是等级,M是线性预测的数量和n的若干意见。


插槽----------Slots----------

D: Of class "array",  D[,,j] is an order-Rank matrix, for j = 1,...,M. Ideally, these are negative-definite in order to make the response curves/surfaces bell-shaped.
D:类"array",D[,,j]是为了Rank矩阵,为j= 1,...,M。理想的情况下,这些都是负面正定的,以使响应曲线/钟形的表面。




Rank: The rank (dimension, number of latent variables)
Rank:秩(维数,潜变量的数量)




lv: n by R matrix
lv:nR矩阵




lvOrder: Of class "matrix", the permutation returned when the function  order is applied to each column of lv. This enables each column of lv to be easily sorted.
lvOrder:类"matrix",置换时返回的功能order被施加到每一列lv。这使得每个列的lv可以很容易地排序。




Maximum: Of class "numeric", the  M maximum fitted values. That is, the fitted values  at the optima for Norrr = ~ 1 models.
Maximum类"numeric",M最大的拟合值。也就是说,在最优Norrr = ~ 1模型的拟合值。




NOS: Number of species.
NOS:物种的数量。




Optimum: Of class "matrix", the values of the latent variables where the optima are.  If the curves are not bell-shaped, then the value will
Optimum:类"matrix",潜变量的值的最优解。如果不是钟形曲线,则该值将




OptimumOrder: Of class "matrix", the permutation returned when the function  order is applied to each column of Optimum. This enables each row of Optimum to be easily sorted.
