5. The ordered probit model 给定 \left( \mu|x\right) 是标准正态分布: Pr\left( y=0|x \right)=Pr\left( y^*\leq \alpha_{1}|x \right)=\Phi\left( \alpha_{1}-x\beta \right) Pr\left( y=1|x \right)=Pr\left( \alpha_{1}\leq y^*\leq \alpha_{2}|x \right)=\Phi\le...
Probit模型顾名思义就是进行了Probit转换,Probit转换是得到一个关于p的单调函数,并且该函数和自变量呈线性关系。 2.二分类Logistic回归 sysuse "auto.dta",clear**一般Logistic回归logit foreign mpg weight**胜算比 (odds)获取的回归logit foreign mpg weight,or 3.多...
1. Logit模型: 它通过对数几率比解释自变量变化对发生概率的影响。Stata操作用"logit y x1 x2 x3"，margins命令可查看边际效应。Logit和Probit模型区别在于逻辑分布的厚尾性。2. Probit模型: 通过正态累积分布函数计算概率，Stata操作为"probit y x1 x2 x3"，同样有margins命令。Probit与Logit相似，但...

應用 Probit model 的實證分析結果得到以下的結論: 性別,年齡,職業等級年消費金額,卡別,年循環金額,信用額度,居住地區在統計顯著水準α=0.01 及0.05 時呈現和違約正相關:至於教育程度,婚姻狀況,年消費金額在α=0.05下都違約呈負相關.此外,也應用 Logit model分析得到幾乎相同的結論,但是其中有一個例外,即年循環...
接着，解释了逻辑回归模型的原理，其中变量的概率比值的对数变化表示随着变量单位变化。同时，比较了逻辑回归与概率模型的异同，指出它们的解释和应用。进一步，阐述了多类别逻辑回归模型的逻辑分布是厚尾，并指出逻辑分布和概率模型之间的主要区别在于逻辑分布假设边际效应变化。随后，介绍了序贯概率模型的概念...

Logit and probit are two regression methods which are categorised under Generalized Linear Models. Both models can be used when the response variables in the analyses are categorical in nature. For the case of the strength of gear teeth data, it can be in terms of counted proportions, such ...
