Avoid variables with short names like $n. Configured minimum length is 3.

Avoid variables with short names like $x. Configured minimum length is 3.

            $y = $numbers[$i+1];

Avoid variables with short names like $y. Configured minimum length is 3.

The property $estimation was declared of type double, but 4 * $inside / $n is of type integer. Maybe add a type cast?
