rmsle: Root mean squared log error

In mikeroswell/MeanRarity: Hill Diversity Estimation and Visualization

Root mean squared log error

Description

Root mean squared log error

Usage

rmsle(x, true_x = mean(Ln(x)))

Arguments

x	positive numeric vector
true_x	numeric scalar, target x value, mean(Ln(x)) by default

Value

scalar, root mean of the squared log ratio of observations to target value

Examples

x <- rlnorm(n = 1e5)
rmsle(x) # should be very close to sdlog of lnorm, 1
y <- rnorm(n = 5000, mean = 12 )
rmsle(y, true_x = Ln(12))
1/12
