Deprecated Functions in the sampleSelection package
废弃的函数在sampleSelection包
译者:生物统计家园网 机器人LoveR
描述----------Description----------
These functions are provided for compatibility with older versions of micEcon/sampleSelection only, and may be defunct as soon as the next release.
这些功能是用于兼容旧版本的micEcon/sampleSelection,并尽快在下一个版本中可能已不存在。
用法----------Usage----------
tobit2(selection, formula, data = sys.frame(sys.parent()),
method="ml",
start=NULL, print.level=0,
y1=FALSE, z=FALSE, y2=FALSE, x=FALSE, model=FALSE,
...)
参数----------Arguments----------
参数:selection
a symbolic formula for the selection equation. The response must be binary variable where 0 corresponds to invisibility of the outcome and 1 to visibility.
一个符号的选择方程公式。响应必须是二元变量,其中0对应的结果和可见性的隐蔽性。
参数:formula
a symbolic formula for the equation of interest.
一个符号公式的方程的利益。
参数:data
an optional data frame containing the variables in the model. By default the variables are taken from environment(formula), typically the environment from which the function is called
一个可选的数据框包含在模型中的变量。默认情况下,变量取自环境(公式),通常的环境,从该函数被调用
参数:method
the method of calculation: Maximum Likelihood ("ml") or Heckman 2-step ("2step")
计算方法:最大似然(“ml”)或赫克曼("2step"2步)
参数:start
numeric, initial values of the parameters. The order is as follows: gamma (selection equation), beta (the equation of interest), sigma, rho (distribution of the error terms) for tobit2;
数值,初始值的参数。的顺序如下:的γ(选择方程),β(方程的利益),σ,ρ(误差项的分布)tobit2;
参数:print.level
information about calculations. 0 – nothing is printed, bigger numbers give more information. print.level is sent further to the maximisation algorithm, see maxNR.
计算信息。 0 - 没有更大的数字印刷,提供更多的信息。 print.level进一步发送到最大化算法,看到maxNR。
参数:y1, z, y2, x, model
logicals. If TRUE the corresponding components of the fit (the selection response, the selection model matrix, the equation response, the equation model matrix and both model frames) are returned.
的逻辑。如果设置为TRUE,拟合(选择响应,选择模型矩阵方程响应,方程模型矩阵和两个模型帧)的对应组件返回。
参数:...
further arguments to the maximisation algorithm, see maxNR.
进一步的最大化算法的参数,请参阅maxNR。

The original help page for these functions is often available at help("oldName-deprecated") (note the quotes).
原来这些功能的帮助页面往往是在help("oldName-deprecated")(注意引号)。
Function tobit2 are for historical compatibility with old versions of micEcon/sampleSelection. Use selection instead.
功能tobit2是历史性的兼容旧版本的micEcon/sampleSelection。使用selection“。
