Details
详情----------Details----------
This function computes the individual tag conditional log-likelihood for each tag. It is necessary for computing both the common conditional log-likelihood and the weighted conditional log-likelihood, which are used to find the common and tagwise (moderated) estimates of the dipsersion parameter. The delta scale for convenience (delta is bounded between 0 and 1).
此函数计算每个标签的个人标签有条件log的可能性。计算双方的共同条件记录的可能性,并加权有条件log的可能性,这是用来寻找共同tagwise(主持)的dipsersion参数估计是必要的。为方便起见,增量规模(Delta界之间的0和1)。
值----------Value----------
vector or matrix of function/derivative evaluations
功能/衍生评价向量或矩阵

commonCondLogLikDerDelta and weightedCondLogLikDerDelta rely on condLogLikDerDelta, and at a user level, estimateCommonDisp and estimateTagwiseDisp are used to estimate the common and (moderated) tagwise dispersion estimates, respectively. condLogLikDerDelta calls condLogLikDerSize, the function that does the mathematical calculations.
commonCondLogLikDerDelta和weightedCondLogLikDerDelta靠condLogLikDerDelta,并在用户层面,estimateCommonDisp和estimateTagwiseDisp来估计的共同(主持)tagwise分散估计,分别。 condLogLikDerDelta要求condLogLikDerSize,做数学计算功能。
举例----------Examples----------
y1<-matrix(rnbinom(10,size=1,mu=10),nrow=5)
v1<-seq(.1,.9,length=9)
ll1<-condLogLikDerDelta(y1,v1,grid=TRUE,der=0,doSum=FALSE)
ll2<-condLogLikDerDelta(y1,delta=.5,grid=FALSE,der=0)
