) of the model are not returned as predictors by default. However, these can be included using additional arguments in the function call, treating predictors are “unique”. As such, if a variable appears as a fixed effect and a random slope, it is treated as one (the same) predictor....
In case hour is not yet included in the model, update themodel by adding this predictor. Generate new data such that you have the hours from 5 to23 in increments of 1. The other numeric predictors enter again with their mean score intothe prediction in the model for carrier UA (United ...
roc函数画图一般只用写两个参数，我一般是这样记的：roc(label,score)label指的是你预测出来的分类变量的类别 score是你用模型预测的变量的得分值

Another useful method to handle errors and warnings is provided by thetryCatch function. This function can be used to check if an R code leads to an error or warning message, and it can be used to skip an error message in order to continue running the code. You can learn more about ...
