描述----------Description----------
用法----------Usage----------
参数----------Arguments----------
参数:param
The vector of regression and not regression parameters.
的回归和回归参数向量。
参数:xdat
(\mathbf{x}_1 , \mathbf{x}_2 , … , \mathbf{x}_n )^\top, where the matrix \mathbf{x}_i,\,i=1,…,n for a given unit will depend on the times of observation for that unit (j_i) and will have number of rows j_i, each row corresponding to one of the j_i elements of y_i and p columns where p is the number of covariates including the unit first column to account for the intercept. This xdat matrix is of dimension (N\times p), where N =∑_{i=1}^n j_i is the total number of observations from all units.
(\mathbf{x}_1 , \mathbf{x}_2 , … , \mathbf{x}_n )^\top,其中矩阵\mathbf{x}_i,\,i=1,…,n对于一个给定的单元将取决于观察的时间该单元(j_i)和将有j_i,对应每一行的行数j_i元素之一y_i和p列p是共变项包括单位的第一列用于拦截。此的XDAT矩阵是尺寸(N\times p),其中N =∑_{i=1}^n j_i是观测各单位的总数。
参数:ydat
(y_1 , y_2 , … , y_n )^\top, where the response data vectors y_i,\,i=1,…,n are of possibly different lengths for different units. In particular, we now have that y_i is (j_i \times 1), where j_i is the number of observations on unit i. The total number of observations from all units is N =∑_{i=1}^n j_i. The ydat are the collection of data vectors y_i, i = 1,…,n one from each unit which summarize all the data together in a single, long vector of length N.
(y_1 , y_2 , … , y_n )^\top,其中的响应数据矢量y_i,\,i=1,…,n都可能有不同的长度为不同的单位。特别是,我们现在有y_i(j_i \times 1),其中j_i是单位i的若干意见。各单位总数的观测是N =∑_{i=1}^n j_i。 ydat是收集的数据向量y_i, i = 1,…,n总结各单位的所有数据一起在一个很长的向量的长度N。
参数:margmodel
Indicates the marginal model. Choices are “poisson” for Poisson, “bernoulli” for Bernoulli, and “nb1” , “nb2” for the NB1 and NB2 parametrization of negative binomial in Cameron and Trivedi (1998).
表示的边际模式。选项是“泊”泊松,“伯努利”伯努利,和“NB1,NB2”为NB1和NB2参数化的负二项分布卡梅伦和Trivedi(1998)。
参数:link
The link function. Choices are “log” for the log link function, “logit” for the logit link function, and “probit” for the probit link function.
链接功能。选择“log”的log链接功能“的罗吉特”为罗吉特连接功能和“概率”的概率链接功能。
