"Accident" in R package vcdExtra gives a 4-way table of frequencies of traffic accident victims in France in 1958. See: help(Accident, package="vcdExtra")

I want to create a binomial distribution with the response variable "result" (died or injured). In particular, I want to create a one-way frequency table with:

-age and frequency of injured

-mode and frequency of injured

-age and frequency of died

-mode and frequency of died

What is the code for making a one-way frequency table?

Solutions

Expert Solution

R code

------

install.packages('vcdExtra')
library(vcdExtra)

head(Accident)

#-age and frequency of injured
aggregate(Freq ~ age, subset(Accident,result=="Injured"), sum)

#-mode and frequency of injured
aggregate(Freq ~ mode, subset(Accident,result=="Injured"), sum)

#-age and frequency of died
aggregate(Freq ~ age, subset(Accident,result=="Died"), sum)

#-mode and frequency of died
aggregate(Freq ~ mode, subset(Accident,result=="Died"), sum)
---------

The `R` package \texttt{moments} gives us two very useful functions; \texttt{skewness} and \texttt{kurtosis}. If data is truly normal, it should have a skewness value of 0 and a kurtosis value of 3. Write an R function that conducts a normality test as follows: it takes as input a data set, calculates a bootstrap confidence interval for the skewness, calculates a bootstrap confidence interval for the kurtosis, then sees if 0 is in the skewness interval and 3 is in the...
