@jstac suggests:
If we think of the maximization in (44.10) of https://python.quantecon.org/optgrowth.html, we are maximizing a function of the form
(*) g(c) = u(c) + h(c).
The problem wit…

Currently, `N`-compounding a distribution is done by sampling the source distribution `N` times, adding the values, and using it as a single sample of a new distribution. The only way to construct a p…

I needed acceleration data from velocity, so as a matter of course I went the lazy route and did 'differentiate' on the Stream before doing anything else. However, after some later mucking around I di…
