I have difficulties understanding the different types of prediction after runningsurvival::clogitin R. I do not think this is due to author's fault, but mainly due to my limited understanding of statistics. So, I wish someone can enlighten me how the predictions were calculated. Noted: T...
R语言 clogit 位于survival 包(package)。 说明 通过最大化条件似然来估计逻辑回归模型。使用 case.status~exposure+strata(matched.set) 形式的模型公式。默认情况下是使用精确的条件似然,提供了常用的近似条件似然以与旧软件兼容。 用法 clogit(formula, data, weights, subset, na.action, method=c("exact",...

Upon running the Hausman test I discovered that my alternatives do in fact violate the IIA properties and I was forced to deviate from the mixed logit model. As for the case specific variables, I'm using the MNP model, but I'm somewhat confused about how to proceed in terms of the ...
The calculation of ρr is as follows. In Formula (5), Lr is the length of the travel route r; Llr is the overlapped length of l and r, and β is a parameter. If this parameter is equal to zero, the C-logit collapses to the MNL route choice model. If this parameter is equal ...
与线性回归中的R^2作用类似 在logistic回归中可以通过Rsquare 和C统计量进行度量 在SAS中通过Rsquare来调用Rsquare。 C统计量自动输出 (4) 模型评价指标汇总 统计量 趋势 拟合 作用 SAS调用命令 备注 AIC 、SC 越小 越好 类似与多元回归中的残差平方和 模型自动输出 ...
