__construct

__construct(string $name, array $shape = [])

of static

of(string $name): Tessero\Stats\MakeDistributionFactory

The family class — SciPy's make_distribution(stats.<name>). Invoke the returned factory with the shape parameters to freeze a distribution object.

make static

make(string $name, array $shape = []): self

One-step construction: make_distribution(stats.X)(**shapes).
