给的指令范例是这样的rqpd(formula, panel = panel(), data = parent.frame(),na.action, subset, contrasts = NULL, control = NULL, ...)
This argument（指panel( )） specifies the panel model configurations. It is created (or passed directly) by the panel
function. It constitutes a named list with options, some of which apply for both FE and CRE models, whereas others are method specific. See details for available options.The panel argument is created with the panel function, e.g.: panel(taus=c(0.1, 0.25, 0.5, 0.75, 0.9), tauw=rep(1/5, 5))
. Options not specified will get the default values. It is not recommended to manually specify the list, as the panel function does some argument validation.
帮助文件里是这样写的：
| tauw (FE): | A vector of weights (summing to 1) for |
| the K weighted components in the FE criterion |
| function. Default is c(.25, .5, .25). |
这个权重代表什么意义呢？第一次接触面板数据分位数回归，谢谢大家赐教。
