examples web page, section on binomial distributions
had not very good plotting using R function
`barplot`

. Threw that away and replaced it with the method of R generic function`plot`

for objects of class`"histogram"`

. Plots look a lot better, but the code is a bit more mysterious. - (posted Dec 7). CLT computer
examples web page, section on bimodal distributions
said
`X`twice where it should have said`Y`. Now fixed. - (posted Dec 7). Deck 7, Slide 39 said PDF instead of DF. Now fixed.
- (posted Dec 4). Deck 7, Slide 23
failed to mention that
`X`and`Y`must be independent random variables. Now fixed. - (posted Oct 29). In homework problem set 7 several cross references to other problems appeared as ??. Now fixed.
- (posted Oct 23). In homework problem 6-7 the cross reference to another problem was ?? and should have ben 6-4. Now fixed.
- (posted Oct 23). The definition of the gamma distribution (Slide 126, Deck 3) failed to mention the parameters must be strictly positive (α > 0 and λ > 0). Now it does.
- (posted Oct 16). Slide 64, Deck 3 about the exponential distribution did not say λ > 0. Now it does
- (posted Oct 16). Slide 65, Deck 3 about the exponential distribution said PMF. Now says PDF.
