先较为详细地介绍单变量线性回归里Bootstrap的应用 进而推广到mutivariate 情形 最后介绍了Bootstrap在预测误差及变量选择方面上的应用 这一章曾经pre过,可以看以前的视频~至此Bootstrap基本内容告一段落,也把研究生的课堂pre的内容陆续上传好了,关于bootstrao还有许多值得深挖的地方,个人认为在testing、变量选择、GLM和...
Bootstrap technique can be readily applied to a situation when we do not assume any distribution for the error and that is why bootstrapping in regression is becoming very popular. In reality the true errors are not known, in that case we need a proper substitute of the residuals. The ...

(for example, a set of regression coefficients), the function should return a vector. Process this function through theboot()function in order to generate R bootstrap replications of the statistic(s). Use theboot.ci()function to obtain confidence intervals for the statistic(s) generated in st...

方法2、两步回归法 (two-step regression) Zhao, Lynch et al. (2010)对传统的逐步检验回归系数方法提出再次思考,但其具体的步骤方法与逐步检验回归系数方法接近,只是取消了第一步中的检验自变量 x 和因变量 y 之间的关系, 代码为: regreadmath //分析 x 和 m 之间的关系 ...
Bootstrap prediction intervals provide a nonparametric measure of the probable error of forecasts from a standard linear regression model. These intervals approximate the nominal probability content in small samples without requiring specific assumptions about the sampling distribution. Empirical measures of ...
