Source: R/drc_Helper.R
ECx_rating.Rd

Assigns qualitative ratings to normalized width values of confidence intervals based on predefined thresholds.

Usage

ECx_rating(x)

Arguments

x

Numeric vector of normalized width values to be rated

Value

Character vector of ratings with the following categories:

  • "Excellent" for NW < 0.2

  • "Good" for 0.2 <= NW < 0.5

  • "Fair" for 0.5 <= NW < 1

  • "Poor" for 1 <= NW < 2

  • "Bad" for NW >= 2

  • "Not defined" for NA or NaN values

Examples

# Basic examples
ECx_rating(c(0.1, 0.3, 0.7, 1.5, 2.5, NA))
#> [1] "Excellent"   "Good"        "Fair"        "Poor"        "Bad"        
#> [6] "Not defined"

# Example with typical normalized widths
nw_values <- c(0.15, 0.45, 0.95, 1.8, 2.5)
ECx_rating(nw_values)
#> [1] "Excellent" "Good"      "Fair"      "Poor"      "Bad"
