`statistics` -> `summary`. We also need to have a better description of the
return value. For example, this is R's doc of `summary.glm`
(https://stat.ethz.ch/R-manual/R-devel/library/stats/html/summary.glm.html):
~~~
summary.glm returns an object of class "summary.glm", a list with components
...
coefficients the matrix of coefficients, standard errors, z-values
and p-values. Aliased coefficients are omitted.
