R: Constructs confidence intervals assuming normal distribution.

ci.t {NCStats}

R Documentation

Constructs confidence intervals assuming normal distribution.

Description

Returns the confidence interval endpoints given an estimate, SE, and df assuming that the estimate follows a normal distribution so that the t-distribution can be used when constructing the CI.

Usage

  ci.t(est, SE, obsdf, conf.level = 0.95)

Arguments

`est`	A value that estimates a parameter (i.e., a statistic).
`SE`	The standard error of the estimate.
`obsdf`	The degrees-of-freedom.
`conf.level`	The level of confidence as a decimal.

Value

Returns a matrix containing the lower and upper values of the confidence interval.

Examples

ci.t(2.96,0.32,14)
