Goodness of fit test
Description
This function is the goodness of fit test
Usage
gofchisq(x, p, conf.level = 0.95)
Arguments
| x | a vector of observed | 
| p | probability of each group | 
| conf.level | confidence level | 
Value
output for goodness of fit test

Examples
x=c(12,9,10,7,12)
prob=c(1/5,1/5,1/5,1/5,1/5)  #1:1:1:1:1
gofchisq(x=x,p=prob)
Independence test
Description
This function is for independence test
Usage
indchisq(O, conf.level = 0.95)
Arguments
| O | an observed matrix has a rows and b columns | 
| conf.level | confidence level | 
Value
output for independence test
