Hi all
I'm reading the doc of the exponential random variable in scipy :
----------------------------------------------------------------------
| Sage Version 4.8, Release Date: 2012-01-20 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
sage: from scipy import stats
sage: stats.expon?
Among other it contains :
expon.pdf(x) = exp(-x) for x >= 0.
scale = 1.0 / lambda
While the *true* text is
expon.pdf(x) = lambda * exp(- lambda*x)
http://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.expon.html
The presence of lambda in that docstring is crucial !
Is it a bug somewhere ?
Have a nice day
Laurent
