is used to calculate the overall cumulative hazard.
Would it not be easier to just add the cumulative hazards up directly? The product integral is only valid if the grid fine enough (extreme case: if the difference in cumulative hazards between two subsequent points is more than one it becomes negative). That also seems to be the approach suggested in https://doi.org/10.1002/sim.3305
Hi,
I ran into issues when using
mssample()with low time grid resolution. Looking a bit intocrsample()I was wondering whyhttps://github.com/hputter/mstate/blob/80cb6fd4afeb0198f6565cc4cdeb0db706f63a2f/R/mssample.R#L315-L316
is used to calculate the overall cumulative hazard.

Is there a reason for using the product?
