sd_wt: Function to calculate weighted standard deviation

In ShellChron: Builds Chronologies from Oxygen Isotope Profiles in Shells

Description

Calculates the standard deviation of a weighted sample set while propagating sample weights through the calculation.

Usage

sd_wt(x, w, na.rm = FALSE)

Arguments

x	Vector containing the values in the set
w	Vector containing the weights to each value (in the same order as x the optimized growth model
na.rm	Should NA values be removed from the set prior to calculation? TRUE/FALSE

Value

The standard deviation of the weighted set of x values

Examples

# Create dummy data
x <- seq(1, 10, 0.5)
w <- c(seq(0.1, 1, 0.1), seq(0.9, 0.1, -0.1))
SDw <- sd_wt(x, w, na.rm = TRUE) # Run the function
