WebOct 28, 2024 · In regression modelling the non-linear relationships between explanatory variables and outcome are often effectively modelled using restricted cubic splines … WebIntroduction. The survPen package was designed to fit hazard and excess hazard models with multidimensional penalized splines allowing for time-dependent effects, non-linear effects and interactions between several covariates (Fauvernier et al. 2024). The linear predictor in survPen is the logarithm of the (excess) hazard.. As the hazard function fully …

WebAug 6, 2024 · Logistic regression model and restricted cubic spline (RCS) were applied to investigate the association of individual metal exposure with renal dysfunction. Weighted quantile sum (WQS) regression and Bayesian kernel machine regression (BKMR) were used to assess the co-exposure effects of the metals. WebA 3-knotted restricted cubic spline (RCS) fitted for Cox proportional hazard regression models is used to analyse the effects of cut-off points of treatment delay on incident poor treatment outcomes.
