We develop a marginalized ZIP model for independent responses to model the population mean count directly, allowing straightforward inference for overall exposure effects and easy accommodation of offsets representing individuals' risk times, as well as empirical robust variance estimation for overall log ...
精确区间估计值.方法应用稳健误差方差估计法(sandwichvarianceestimator)来校正相对危险度(RR)的估计方差,并 通过SAS程序中GENMOD过程的REPEATED语句实现修正poisson回归.此外,采用不同的统计方法对5个虚拟的研 究数据进行了分析比较.结果以分层的Mantel—Haenszel法为标准参照,修正poisson回归对aRR点和区间估计均较为 理想,...
I'm trying to fit a Poisson regression model with a constant off-set term, which means that the variance of the off-set term is zero and MPlus prints an error. Here is an example in code: VARIABLE: NAMES ARE a1-a3 b1-b3 off1-off6 off_a1-off_a3 off_b1-off_b3; COUNT ARE ...

analysis of variance (ANOVA), split plot analysis, generalized linear model (glm), generalized linear mixed model (glmm) using R with R markdown, and with the standard statistical analysis software SAS/JMP. The goal is to demonstrate good analysis practices for categorical data by comparing the...
Table 4.Monte Carlo simulation regression results for AUC—g and AUC—i. With AUC—i as the dependent variable, for the largest sample size (n = 500), bias did not exceed 2%. However, there was much instability in parameter estimation in this model. Indeed, as the sample size decreased...
