team

NCAA football team

rank

rank based on fumbles per game through games on November 26, 2010

W

number of wins through games on November 26, 2010

L

number of losses through games on November 26, 2010

week1

number of fumbles on November 6, 2010

week2

number of fumbles on November 13, 2010

week3

number of fumbles on November 20, 2010

Examples

data(Fumbles)
m <- max(Fumbles$week1)
table(factor(Fumbles$week1,levels = 0:m))
favstats( ~ week1, data = Fumbles)
# compare with Poisson distribution
cbind(
		  fumbles = 0:m,
		  observedCount = table(factor(Fumbles$week1,levels = 0:m)),
		  modelCount= 120* dpois(0:m,mean(Fumbles$week1)),
		  observedPct = table(factor(Fumbles$week1,levels = 0:m))/120,
		  modelPct= dpois(0:m,mean(Fumbles$week1))
	) %>% signif(3)
showFumbles <- function(x, lambda = mean(x),...) {
  result <-
    gf_dhistogram( ~ week1, data = Fumbles, binwidth = 1, alpha = 0.3) %>%
    gf_dist("pois", lambda = mean( ~ week1, data = Fumbles) )
  print(result)
  return(result)
