一土 The log-binomial model is simply a binomial generalised linear model (GLM) with a log link function. It is particularly popular in biostatistical and epidemiological applications as an alternative to logistic regression, since the parameters are adjusted relative risks rather than adjusted odds r...

Subjectst: glm, link(log) family(?) DateMon, 19 May 2003 08:53:06 -0700 (PDT) Hi, I am modeling health care expenditures using glm. Furthermore, I am using the model to generate predictions of health care expenditures, so the variance component is quite important to me. A "Park tes...
In CFA and log-linear models, the expected frequencies are calculated according to the underlying null model, which is specified in the design matrix using the generalized linear model (GLM). In this chapter, log-linear modeling and hierarchical log-linear modeling are presented. Hi-log modeling...
然后我们用glm函数来实现相加模型的思想。 glm(y~bs(x1,degree=1,df=3)+bs(x2,degree=1,df=3), family=binomial(link = v = outer(u,u,p) image(u,u,v, ",col=clr10,breaks=(0:10)/10) 1. 2. 3. 现在,我们能够得到一个“完美”的模型,所以,结果似乎不再连续 ...

拟合GLM模型: # 拟合GLM模型model<-glm(log_y~x,data=data,family=gaussian(link="log")) 1. 2. 在上面的代码中,我们使用了glm函数,指定了因变量log_y与自变量x之间的关系,并将分布设定为正态分布(family = gaussian),链接函数为对数链接(link = "log")。
You can also calculate log likelihood in the following manner: [beta = glmfit(X,y,'poisson','link','log'); mu = glmval(beta,X,'log') nll = -sum(log(poisspdf(y,mu))) 댓글 수: 0 댓글을 달려면 로그인하십시오. ...
