Percentile rank — percentile

The bounds of a percentile rank are > 0 and < 100.

A percentile rank here is the proportion of scores that are less than the current score.

$$PR = (c_L + 0.5 f_i) / N * 100$$

Where

$c_L$ is the frequency of scores less than the score of interest

$f_i$ is the frequency of the score of interest

Usage

percentile_rank(x)

Arguments

x: A vector of values to rank

Value

A percentile rank between 0 and 100

Details

Computes a percentile rank for each score in a set.

Examples

percentile_rank(0:9)
#>  0  1  2  3  4  5  6  7  8  9 
#>  5 15 25 35 45 55 65 75 85 95 
x <- c(1, 1, 2, 5, 7, NA_integer_, 7, 10)
percentile_rank(x)
#>     1     1     2     5     7  <NA>     7    10 
#> 12.50 12.50 31.25 43.75 62.50    NA 62.50 81.25 
# compare to dplyr
# dplyr::percent_rank(x) * 100
