Exception for b parameter of renormalized beta distribution

• Falling back on racket egraph because egg-herbie package not installed

\[0.0 \lt m \land 0.0 \lt v \land v \lt 0.25\]

Math

\[\left(\frac{m \cdot \left(1 - m\right)}{v} - 1\right) \cdot \left(1 - m\right)\]

C

double f(double m, double v) {
        double r128 = m;
        double r129 = 1.0;
        double r130 = r129 - r128;
        double r131 = r128 * r130;
        double r132 = v;
        double r133 = r131 / r132;
        double r134 = r133 - r129;
        double r135 = r134 * r130;
        return r135;
}
