Question

我一直在尝试使用mlogit，Zelig和texreg从stargazer模型中提取我的摘要统计信息。

memisc引发了以下错误：

texreg

texreg(MLogitRes3) Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ‘extract’ for signature ‘"vglm"’引发了以下错误：

stargazer

stargazer(MLogitRes3) Error in objects[[i]]$zelig.call : $ operator not defined for this S4 class（使用memisc函数）抛出了最后一个错误：

mtable

这些软件包中是否都不支持mtable(MLogitRes3) Error in UseMethod("getSummary") : no applicable method for 'getSummary' applied to an object of class "c('vglm', 'vlm', 'vlmsmall')"中的mlogit个选择模型？我是否可以选择将我的摘要统计信息导出到LaTex其他地方可用的表中？

你最近有没有尝试重现这个？我刚查看了texreg::extract.zelig的代码，它似乎有mlogit的方法：

function (model, include.aic = TRUE, include.bic = TRUE, include.loglik = TRUE, 
    include.deviance = TRUE, include.nobs = TRUE, include.rsquared = TRUE, 
    include.adjrs = TRUE, include.fstatistic = TRUE, ...) 
    ...
    else if ("mlogit" %in% class(model)) {
        coefficient.names <- rownames(s@coef3)
        coefficients <- s@coef3[, 1]
        standard.errors <- s@coef3[, 2]
        zval <- s@coef3[, 3]
        significance <- 2 * pnorm(abs(zval), lower.tail = FALSE)
        gof <- numeric()
        gof.names <- character()
        gof.decimal <- logical()
        if (include.loglik == TRUE) {
            lik <- logLik(model)[1]
            gof <- c(gof, lik)
            gof.names <- c(gof.names, "Log Likelihood")
            gof.decimal <- c(gof.decimal, TRUE)
        }
        if (include.deviance == TRUE) {
            dev <- deviance(s)
            if (!is.null(dev)) {
                gof <- c(gof, dev)
                gof.names <- c(gof.names, "Deviance")
                gof.decimal <- c(gof.decimal, TRUE)
            }
        }
        if (include.nobs == TRUE) {
            n <- nrow(model$data)
            gof <- c(gof, n)
            gof.names <- c(gof.names, "Num. obs.")
            gof.decimal <- c(gof.decimal, FALSE)
        }
        tr <- createTexreg(coef.names = coefficient.names, coef = coefficients, 
            se = standard.errors, pvalues = significance, gof.names = gof.names, 
            gof = gof, gof.decimal = gof.decimal)
        return(tr)
    }
    ...
}

无论如何，如果您仍然遇到问题，可能需要阅读Section 6 of the texreg article，其中提供了有关如何为任何模型定义自己的extract方法和/或编写软件包作者的说明（Philip Leifeld）获得支持。
