I am trying to build a glm model using Glm() from rms package in R. But I don't know the correct expression in Glm formula for the indicators. Allow me use iris data as an example, In the base R glm function, my code works and it is like below: model1 = glm(Sepal.Length~Sepa...

stay within the Grammar of Graphics by providing functions that can be used asggplot2layers. An example of one of these functions is thestat_fitted_resid()function. With this function, we can take a closer look at just the fitted vs. residual plot from the mixed model fit in Example 1....
The R function glm uses step-halving to deal with certain types of convergence problems when using iteratively reweighted least squares to fit a generalized linear model. This works well in some circumstances but non-convergence remains a possibility, particularly with a nonstandard link function. I...

R语言编码的基本知识。 进行绘图和数据处理的基本知识。 广义线性模型(GLM)简介 对于y是连续值得情况,我们可以用这种方式处理,但当y是离散值我们用普通线性模型就不合适了,这时我们引用另外一种模型 --- Generalised Linear Models 广义线性模型。 为了获取GLM模型,我们列出3个条件: ...

R默认安装了基础包,其中包括运行GLM的glm函数。glm的参数与lm的参数相似:公式和数据。然而,glm需要一个额外的参数:family,它指定了结果变量的假设分布;在family中我们还需要指定链接函数。family的默认值是gaussian(link = "identity"),这导致了一个线性模型,相当于由lm指定的模型。在二元逻辑回归的情况下,glm要求我...
