making points on the stphplot smaller msize(vtiny)

[Martin Imelda Borg]

Hello,

I'm trying to assess PH with univariate analysis - using log log Kaplan meier survival curves - stphplot-

However it's difficult to subjectively assess parallelism and assess PH due to the size of the points . I tried to resize them as one would do with a scatter plot using the code below

stphplot, by(gender) nonegative nolntime msize(vtiny)

//Stata error: option msize(not allowed)

Is it possible / are there alternatives?

thanks i wonder why this isn't in the help file.

It is, otherwise how else would I know about it? Look at

help stphplot

where you will find
