An application question for a change: I need to produce pseudorandom numbers drawn from a lognormal distribution (see http://www.itl.nist.gov/div898/handbook/eda/section3/eda3669.htm). Does anyone have existing code for this in Numeric or numarray?
In [24]: scipy.stats.lognorm? Type: instance Base Class: scipy.stats.distributions.lognorm_gen String Form: <scipy.stats.distributions.lognorm_gen instance at 0x45187f0c> Namespace: Interactive Docstring: A lognormal continuous random variable. Continuous random variables are defined from a standard form chosen for simplicity of representation. The standard form may require some shape parameters to complete its specification. The distributions also take optional location and scale parameters using loc= and scale= keywords (defaults: loc=0, scale=1) I'm not a stats person, so perhaps this one is not enough for you. If that's the case, sorry about the noise. Best, f
