Power mean of vector elements — power

power_mean() calculates the power mean of a set of values.

power_mean(values, order = 1, weights = rep(1, length(values)))

Arguments

values: Values for which to calculate mean.
order: Order of power mean.
weights: Weights of elements, normalised to 1 inside function.

Value

Weighted power mean

Details

Calculates the order-th power mean of a single set of non-negative values, weighted by weights; by default, weights are equal and order is 1, so this is just the arithmetic mean. Equal weights and a order of 0 gives the geometric mean, and an order of -1 gives the harmonic mean.

Examples

values <- sample(1:50, 5)
power_mean(values)
#> [1] 17.8
