Add shape param for LogN distribution
Opened this issue · 1 comments

It is currently not possible to set the "usual" loc
and scale
params on the log scale for the LogNormal distribution.
loc
is usually 0, and scale
should usually set to exp(mu)
For details, see http://nbviewer.ipython.org/url/xweb.geos.ed.ac.uk/~jsteven5/blog/lognormal_distributions.ipynb

While this is true for the built-in "LogN" function, you can input your own distribution directly like
a = rv(scipy.stats.lognorm(shape, loc=0, scale=scale))
I'll have to look into this more to justify the correction to the convenience function.
