Dear
Dr. Gunter,
Thanks for your reply. Here comes my thinking "In practice
Sturges' rule is applied by dividing the sample range of the data into the
prescribed number of equal-width bins....Sturges' rule is widely recommended in
introductory statistics texts and is often used in statistical packages as a
default" (Scott, 1992, p.48). I, from the very little I know in statistics,
conclude cut(x,br) assumes normal distribution. I understand that the underlying
distribution in the derivation of Sturges' rule is normal density. I may be
wrong.
Kind regards,
Patricia.
