Dear Nick and Maarten,

Thanks for your help and the references.

Best,

Philipp

Quoting Nick Cox <[email protected]>:

-graph dot- is not the only option here. You could use -twoway dot-.
There is much discussion of this approach in Stata Journal 8(2):269--289
(2008).

Either way, you need to enter your covariate names and hazard ratios as
new variables.

How to sort is up to you.

I did a piecewise constant exponential model (with 7 covariates) and
would like to visualize the results! Is it possible to use the
graph dot command to plot the hazard ratio of covariates (in a
particular order - from high to low!)? If so, how do I do that?

It should look like this:

                        covariate6  |...........o....
                        covariate1  |.........o......
                        covariate3  |.......o........
                                    +----------------
                                    hazard ratio


the command to plot should be:

graph dot numerical variable , over(categorical variable
[,sort((stat)varname)])

but my problems are:
a) how to introduce my covariates instead of a categorical var?
b) how to sort?
