bias_per {forestmangr}

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.

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)
