      First, I'd write down a model for how your stochastic process 
relates to independent, normal observations with mean 0 and standard 
deviation 1.  You want a lognormal series, so I'd start by generating a 
normal series and the compute 'exp' of that.  If you'd like more help 
from this listserve, please provide commented, minimal, self-contained, 
reproducible code, as suggested in the posting guide 

      Hope this helps.
