se: Standard Error

In guf: Generally Useful Functions

Description

The Standard Error ('se') of a numerical vector x.

Usage

se(x, na.rm = TRUE)

Arguments

x	A vector of numerical values, be it integers and/or real numbers.
na.rm	A Boolean, indicating whether NAs need to be removed from x before calculating the Standard Error; defaults to TRUE

Value

One real number, being the Standard Error.

Examples

my_vector = c(1, 3, 4, 7.5, 8)
var(my_vector); sd(my_vector); se(my_vector)
my_vector = c(NA, 3, 4, 7.5, 8)
var(my_vector); sd(my_vector); se(my_vector)
# note that se() by default leaves out NAs. But compare:
var(my_vector); sd(my_vector); se(my_vector, na.rm=FALSE)
