SuccessRate

SuccessRate calculates the Wilson-confidence interval for a sucess-rate (using prop.test).

SuccessRate(FAC, SUCCESS = 2, CONF.LEVEL = 0.95, DIGITS = 1)

Arguments

FAC	is a factor. Will be converted to a factor if not a factor.
SUCCESS	=2, factor level that defines success. If numeric, the respective level of FAC is assumed.
CONF.LEVEL	=0.95, desired confidence level
DIGITS	=7 number of digits

Value

data.frame with SuccessCategory, Number of Successes, Nvalid, Rate estimate in procent and lower and upper of the CONF.LEVEL confidence interval.

Examples

if (FALSE) {
SuccessRate(rbinom(453,1,0.33))
x<-sample(c("Male", "Female","Inter"),453,replace=T, prob = c(.503,.494,.003))
x<-factor(x,levels = c("Male", "Female","Inter"))
table(x)
SuccessRate(x,DIGITS=2,SUCCESS=3)
SuccessRate(x,DIGITS=3,SUCCESS=3,CONF.LEVEL=.9)
}
