At the end of the section, since the PDF is
$$ p(r)=\begin{cases} 0, & r < 0\ \frac{3}{8} r^2 & 0 \leq r \leq 2\ 0 & 2 < r \end{cases} $$
and the corresponding CDF is
$$P(r) = \frac{r^3}{8}$$
then we have
$$y=\frac{r^3}{8}$$
and solving for $r$ in terms of $y$ we get
$$r^3=8y$$
$$r=(8y)^\frac{1}{3}=2y^\frac{1}{3}$$
so the correct ICD should be
$$P^{-1}(x) = ICD(d) = 2d^\frac{1}{3}$$
instead of
$$P^{-1}(x) = ICD(d) = 8d^\frac{1}{3}$$
Please delete this issue if I am mistaken somewhere. Thank you for your great work!
