Hi Anne,

Thanks for the clarification. If you simply need to generate samples from a truncated lognormal distribution, I would not recommend you use quoFEM (Although we can do it by generating standard uniform samples and providing a model that transforms the samples to truncated lognormal space)

Instead, to my understanding, the 'rejection sampling' described below seem to be the quickest way of getting samples from truncated lognormal:

1. Generate a larger set of samples from the original lognormal distribution, for example, using stats.lognorm.rvs()

2. Discard all the samples below the truncation threshold and use only the ones within the valid range.

Please let me know if I am missing something or if you wanted to get the PDF or CDF of the truncated lognormal distribution instead of its samples.

Thanks,
