Multinomial Logistic Regression
多项式Logistic回归
译者:生物统计家园网 机器人LoveR
描述----------Description----------
Fits a multinomial logistic regression model to a nominal scale outcome.
多项式logistic回归模型适合名义规模的结果。
用法----------Usage----------
mlogit(formula, data, control = glm.control())
参数----------Arguments----------
参数:formula
An object of class formula containing a symbolic description of the model to be fit. See the documentation of formula for details.
一个类的对象formula包含模型的一个象征性的描述是合适的。看到formula细节的文件。
参数:data
An optional data frame containing the variables in the model. If not found in 'data', the variables are taken from the environment from which 'mlogit' is called.
一个可选的数据框包含在模型中的变量。如果没有发现在“数据”,取自被称为“mlogit环境变量。
参数:control
A list of parameters for controlling the fitting process. See the documentation of glm.control for details. </table>
一个装修过程控制参数的列表。看到glm.control细节的文件。 </ TABLE>
Details
详情----------Details----------
The function mlogit fits a multinomial logistic regression model for a multi-valued outcome with nominal scale. The implementation and behaviour are designed to mimic those of glm, but the options are (as yet) more limited. Missing values are not allowed in the data.
在的功能mlogit适合一个多值的结果与标称规模的多项式Logistic回归模型。实施和行为的设计模仿那些glm,但选项(还)较为有限。不允许在数据缺失值。
The model is fitted without using a reference outcome category; the parameters are made identifiable by the requirement that the sum of corresponding regression coefficients over the outcome categories is
该模型装有参数是由识别的要求,成果类别相应的回归系数总和是不使用参考结果类别;
值----------Value----------
An object of (S4) class mlogit. The class has slots: coefficients (matrix), standard.err (matrix), fitted.values (matrix), x (matrix), y (matrix), formula (formula), call (call), df.null (numeric), df.residual (numeric), null.deviance (numeric), deviance (numeric), iter (numeric), converged (logical).
(S4)类mlogit的对象。类有槽:系数(矩阵),standard.err(矩阵),fitted.values(矩阵),X(矩阵),Y(矩阵),公式(公式),通话(检测),df.null(数字) df.residual(数字),null.deviance(数字),越轨(数字),国际热核实验堆(数字),融合(逻辑)。
Methods implemented for the mlogit class are coefficients, fitted.values, residuals and which extract the relevant quantities, and summary, which gives the same output as with a glm
mlogit类实现的方法是coefficients,fitted.values,residuals和提取相关的数量和summary,给出了一个相同的输出glm
