## S3 method for class 'htest':
confint(object, parm, level, ...)
pval(x, ...)
## S3 method for class 'htest':
pval(x, digits = 4, verbose = FALSE, ...)
stat(x, ...)
## S3 method for class 'htest':
stat(x, ...)

Arguments

object

a fitted model object or an htest object.

parm

a specification of which parameters are to be given confidence intervals, either a vector of numbers or a vector of names. If missing, all parameters are considered.

level

x

An object of class htest.

digits

Examples

confint(t.test(rnorm(100)))
pval(t.test(rnorm(100)))
stat(t.test(rnorm(100)))
confint(var.test(rnorm(10,sd=1), rnorm(20, sd=2)))
pval(var.test(rnorm(10,sd=1), rnorm(20, sd=2)))
if (require(mosaicData)) {
data(HELPrct)
stat(t.test (age ~ shuffle(sex), data=HELPrct))
# Compare to test statistic computed with permuted values of sex.
do(10) * stat(t.test (age ~ shuffle(sex), data=HELPrct))
