举个例子,下图为一个原始的COX模型结果,可见优惠券的数量(total_number)可以明显的降低用户流失风险,且每增加一个优惠券,风险会变为原来的0.94倍。 至此,一个完整的生存模型完成了。 参考文献 Analyzing Customer Churn - Cox Regression https://cran.r-project.org/web/packages/survival/vignettes/timedep.pdf l...

For continuous clinical variables, we applied a time-dependent Cox regression model. Two types of models were applied—a linear and nonlinear model with restricted cubic splines—to assess the U-shaped association. Statistical significance (set at 0.05) for the nonlinearity was tested by comparing ...
