weighted_variance_univariate: Calculate the variance of numbers (univariate)

In rchan26/hierarchicalFusion: Divide-and-Conquer Monte Carlo Fusion

Calculate the variance of numbers (univariate)

Description

Calculation of the weighted variance of numbers

Usage

weighted_variance_univariate(x, x_mean, precondition_values)

Arguments

x	vector of sampled sub-posterior values
x_mean	weighted mean of sampled sub-posterior values
precondition_values	precondition values associated to each sub-posterior

Value

the weighted variance of numbers

Examples

x <- rnorm(4, 0, 1)
precondition_vals <- c(1, 2, 3, 4)
x_mean <- weighted_mean_univariate(x = x,
                                   weights = 1/precondition_vals)
weighted_variance_univariate(x = x,
                             x_mean = x_mean,
                             precondition_values = precondition_vals)
