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.
