McBreach log-normal distribution

[Leilani]

I have been playing around with the McBreach software (such amazing software!) and am getting some issues when using the log-normal distribution. When I use this distribution, McBreach tends to sample towards the extremes. I have tried this for various breach parameters and have also tried adjusting my mode and mean values to follow a more “uniform distribution” shape (at first I though maybe my mode was too close to my absolute minimum). I am definitely getting statistical convergence so that’s not the issue. Has anyone else experienced this? How can I overcome this?
