CI: Confidence Interval of Mean

In JVAdams/jvamisc: A Collection of Utility Functions

Description

Calculate the confidence interval or limits of the mean using the t distribution.

Usage

CI(x, alpha = 0.05, keepMean = TRUE, limits = TRUE, prefix = "", na.rm = FALSE)

Arguments

x	Numeric vector of sample observations.
alpha	Numeric scalar denoting significance level, default 0.05.
keepMean	Logical scalar indicating if the mean should be returned with the confidence interval/limits, default TRUE.
limits	Logical scalar indicating if the limits should be returned (otherwise a single interval is returned), default TRUE.
prefix	Character scalar to be used in assigning names to the returned value, default "".
na.rm	Logical scalar indicating if missing values should be removed before calculations, default FALSE.

Value

A named vector of the mean (if keepMean=TRUE) and the (1 - alpha)*100 interval (if limits=FALSE). Names are the prefix concatenated to "mean", "lo", and "hi".

Examples

CI(1:10)
