Book 1 - Page 63/64 Density instead of distribution

[zderbazi]

The following comments concern the online version dated November 23, 2024.

In p63, there are two issues under 2.7.4 Beta distribution:

1. The less serious one which can be ignored is

"The beta distribution has support over the interval [0, 1] and is defined as follows:

$${\rm B}(x | a, b) = \frac{1}{{\rm B}(a,b)} x^{a-1} (1-x)^{b-1}.$$
"

• This is the definition of the density. Perhaps you could change "and is defined as follows" to "and its pdf is defined as follows".

Similar observation applies to the Gamma distribution and co in pages 64-65.

2. In p63, further down under the same subsection

"We require $a, b > 0$ to ensure the distribution is integrable (i.e., to ensure ${\rm B}(a, b)$ exists).”

• Distribution should be pdf or density.
