klaR包与e1071包都可以做朴素贝叶斯分类,本次试验中,klaR包在使用的时候会出现警告,但不影响预测(Both the klaR package and the e1071 package can be used as a simple Bias classification. In this experiment, the klaR package will be warned when it is used, but it does not affect the prediction.)
结合案例来描述每一种统计学模型,解释如何开展数据分析,讨论采用模拟手段来检验模型,这是模型开发与评估中的重要方面,给出多层回归模型(如多层ANOVA、多层线性回归和广义多层模型),指导如何用R语言采实现诸多方法,在线提供书中所用到的数据集和R语言脚本。(Combined with the case to describe each kind of statistical model, how to carry out data analysis and interpretation, discusses the use of simulation to test the model, this is an important aspect of the development and evaluation of the model, given the multi regression model (such as multilayer ANOVA, multi linear regression and generalized multi model), how to achieve a lot of mining method with the R language guide online provide the data set and the R script used in the book.)
主要利用R语言进行广义加法模型,进行回归预测(This paper mainly uses R language to carry on the generalized additive model, and carries on the regression forecast)
