**Discussion:**

In my opinion the choice of name for the `t` parameter of the `binomial_distribution`
is very unfortunate. In virtually every internet reference, book and software implementation
this parameter is called `n` instead, see for example Wikipedia, Mathworld, Evans et al. (1993)
Statistical Distributions, 2nd E., Wiley, p. 38, the R statistical computing language, p. 926,
Mathematica and Matlab.

Similarly, the choice of `k` for the parameter of the negative binomial distributions is rather unusual.
The most common choice for the negative binomial distribution seems to be `r` instead.

Choosing unusual names for the parameters causes confusion among users and makes the interface unnecessarily inconvenient to use.

**Possible resolution:** For these reasons, I propose to change the name of the respective parameters
to `n` and `r`.

In N2424. NAD It has been around for a while. It is hardly universal, there is prior art, and this would confuse people.

**Proposed resolution:**

See N2424 for the proposed resolution.
