Same for mac, is that relevant?

Same for mac, is that relevant?

I do not think it is critical. I suspect a random seed problem.

If at all, it could have an impact on the automatic parameter estimation if you use it and which needs to be critically assessed anyway.

[ctroupin]

Shall we edit the test

≈(median(fitlenxy), lenx, rtol = 0.3)

to have that test passing?
