Hello,

There is a pool of quicker alternatives: Categorized Plots, Partial Residual Plots, Lowess Smoothing and Spline Regression.

From my personal experience, I would try at first Partial Residual Plots!

Thank you Igor! Could you perhaps supply R-code for the mentioned alternatives, compatible with the output from the function clogit(). Best regards, Erik

Here you go for "Partial Residual Plots". Open the code in a ".Rmd" (R Markdown) file in RStudio.

```{r}

install.packages(c("survival", "rms"))

library(survival)

library(rms)

```

```{r}
