Bias of an estimator in percentage

Description

Function for calculating the bias of an estimator.

Usage

bias_per(df, y, yhat, na.rm = TRUE)

Arguments

df	a data frame.
y	Quoted name of the variable representing the observed values in the data frame. If a data frame is not provided, y can also be a numeric vector.
yhat	Quoted name of the variable representing the estimated values in the data frame. If a data frame is not provided, yhat can also be a numeric vector.
na.rm	a logical value indicating whether NA values should be stripped before the computation proceeds. default: TRUE

Details

Function for calculating the bias of an estimator, given the observed values, and the estimated values.

Value

Numeric vector with the bias value, in percentage.

Examples

library(forestmangr)
data("exfm11")
head(exfm11)

# Bias of an estimator, given the data frame and quoted variable names:
bias_per(exfm11, "TH", "TH_EST3")

# Bias of an estimator, given the vectors for observed and estimated values:
bias_per(y = exfm11$TH, yhat = exfm11$TH_EST3)
