R中的频率权重(使用lme4的多级) [英] Frequency weights in R (multilevel using lme4)

问题描述

我正在用lme4构建一个多层次的模型(两个层次:一个班级和一个具有教育数据的学生层次).我正在使用ICCS 2009数据: http://www.iea.nl/iccs_2009.html). ICCS 2009建议使用权重.我将校内学生体重"作为班级和学生水平体重因子的乘积.我还使权重之和等于样本量.我的问题:如何在R中指定要将此权重用作频率权重.我必须使用调查"软件包吗?

I'm building a multilevel model with lme4 (two levels: a class and a student level with educational data). I'm using the ICCS 2009 data: http://www.iea.nl/iccs_2009.html). ICCS 2009 advise the use weights. I made a "within-school student weight" as the product of the class and student level weight factors. I also made the sums of the weights equal to the sample size. My question: how can I specify in R that I want to use this weight as a frequency weight. Do I have to use the "survey" package?

推荐答案

iccs是一个复杂的调查(请参阅用户指南的第3章)，R调查包不能(但尚不能)处理多级模型-您可以阅读此帖子的底部了解更多信息

iccs is a complex survey (see chapter 3 of the user guide) and the R survey package cannot (yet) handle multi-level models - you can read the bottom of this post for more detail

如果您不关心标准错误，则lme4中的大多数函数都有一个weights=参数，应该为您提供合理的猜测..但是标准错误都将是错误的.

if you don't care about standard errors, most of the functions in lme4 have a weights= argument that should give you reasonable guesses.. but the standard errors will all be wrong.

iccs 2009用户指南在pdf第33页，共112页上推荐了其他软件.
