摘要
针对R中没有函数可以实现模型似然比检验、模型的拟合度等问题,编写了拟似然检验、拟合度的R代码,运用实例给出分位数回归在R中实现的一般流程,为以后分位数回归的算法研究提供了重要参考.
As there isn＇t function realizing quasi-likelihood-ratio model test and goodness-of-fit in R, R-codes of quasi-likelihood-ratio and goodness-of-fit programmed are put forward. General process of quantile regression is developed based on an represent-ative example for providing important reference on quantile regression algorithm research.
