gm_95CI: Calculate the geometric 95 percent confidence interval

In shirewoman2/LaurasHelpers: Miscellaneous Helper Functions for Common PK or Analytical Chemistry Tasks

Calculate the geometric 95 percent confidence interval

Description

gm_95CI takes as input a numeric vector and returns the geometric 95 percent confidence interval

Usage

gm_95CI(x, na.rm = TRUE, zero.propagate = FALSE)

Arguments

x	A vector of numbers
na.rm	Should NA values be removed? (logical)
zero.propagate	Should zeroes be propagated? (logical)

Details

Because this calculation log-transforms the input data:

1. values of zero must be either omitted (zero.propagate = FALSE) or, if included (zero.propagate = TRUE), the result will be NA, and

2. the function is undefined for negative numbers.

Value

Returns a list of numbers

Examples

gm_95CI(rnorm(10, 5, 1))
gm_95CI(c(4, 3, 7, 19, 4, 0), zero.propagate = TRUE)
gm_95CI(c(4, 3, 7, 19, 4, 0), zero.propagate = FALSE)
