- p.343, right, l.-8 and p.344, right, l.20:
skewed to the right instead of skewed to
(In fact, the terms left and right skewed are not used uniformly in the
same way. A tower is skewed to the left if its upper end leans to the
left, and this use of the words contradicts their usual use in statistics.
A clearly defined term is "positively skewed" for such distributions.)
- p.344, Fig.3.(b)
The μ and σ used here are scaled versions of the usual
μ and σ used throughout the paper, since logs to base 10 are used.
The usual parameters are larger than these, by a factor
log(10) = 2.3.
- p.345, l.5 of the box:
mean ... exp(μ+σ2/2)
mean ... exp(μ+σ/2)
- General problem for the pdf version:
μ is often represented as ∝
