calc.foldrange {hbim}

Calculate stadard error and fold-range from confidence interval

Description

Given a confidence interval and sample size, we find the standard error assuming confidence limits are calculated on the log10 responses by either normal confidence limits or t-distribution confidence limits. The fold-range is also output by either methods.

Usage

calc.foldrange(n, lower, upper, conf.level = 0.95)

Arguments

n

vector of sample size(s) used to create confidence intervals

lower

vector of lower confidence limits

upper

vector of upper confidence limits

conf.level

confidence level, default=.95

Details

See vignette("hbimdetails")

Value

A vector (or matrix) with elements (or columns)

n

sample size

lower

lower confidence limit

upper

upper confidence limit

s.byt

standard deviation assuming confidence intervals calculated by t-distribution

s.byz

standard deviation assuming confidence intervals calculated by normal distribution

foldrange.byt

fold-range assuming confidence intervals calculated by t-distribution

foldrange.byz

fold-range assuming confidence intervals calculated by normal distribution

Examples

## sample size=43, lower cl=65, upper cl=85
calc.foldrange(43,65,85)
