regression modelsresidualsIn this article, we propose a mean linear regression model where the response variable is inverse gamma distributed using a new parameterization of this distribution that is indexed by mean and precision parameters. The main advantage of our new parametrization is the ...
Likelihood ratio tests for discovering the best parametric regression model among the parametric families of lifetime distributions is performed in each stratum. Thus, the proposed method can identify the model for each subsample if the whole sample consists of subsamples having different regression ...
In this article, we proposed some influence diagnostics for the gamma regression model (GRM) and the gamma ridge regression model (GRRM). We assess the impact of influential observations on the GRM and GRRM estimates by extending the work of Pregibon [Logistic regression diagnostics. Ann Stat. ...
Poisson regression and Grey Model(GM(1,N))were used to analyze the correlation between hypospadias and environmental data. 方法:利用已收集的全国 31个省市 1988～ 1992年和 1996～2 0 0 0年的男性尿道下裂监测资料以及 1987～ 1992年和 1995～ 2 0 0 0年的环境因素监测资料 ,同时采用收集的各省地理...

plot(model,which=1) 1. 结果解释 最后,我们可以通过模型的系数来解释自变量对于因变量的影响。例如,如果得到hp的系数为-0.03,则表示每增加一个马力,mpg将减少0.03。 总的来说,Gamma回归是一种适用于非负数据的回归分析方法,通过R语言可以很方便地进行建模和分析。在实际应用中,我们需要根据具体问题选择合适的自变...

On that basis optimality results can be transferred from one model to the other and vice versa. Additionally by means of the general equivalence theorem optimality can be characterized for multiple regression by a system of polynomial inequalities which can be solved analytically or by computer ...
The results of an empirical analysis on a firms dataset reveal that the advanced Gamma–lindley cure model has a rather effective performance in terms of default time prediction compared to Exponential, Gamma, Weibull, and Cox proportional hazards regression modeling specifications, which yield a ...
