fn_freqw

This is a methodological function to calculate the percentage frequencies of weights by model adjusted using the robust regression approach.

Usage

fn_freqw(df, breaks, right = FALSE)

Arguments

df

A vector of data values.

breaks

A vector with class intervals

right

Logical, indicating if the intervals should be closed on the right (and open on the left) or vice versa.

Value

A table with frequencies by class interval is returned.

Details

The function calculates the relative frequency distribution using the function `fn_freq` from `Morefi` package.

For `fn_freq`, the breaks object must be defined. For this work, a sequence of breakpoints of equal distance is used. To incorporate the number of non-weighted values (wi=1), a class interval "1" is added to the sequence.

Examples

# In the df object, 30 random values between 0.1 and 0.9 are generated and
# five values equal to 1 are added.
# The breaks object is defined to include non-weighted values (wi=1), weighted
# values (wi lower than 1 and equal to or higher than 0.25), and outliers
# (wi lower than 0.25).

if (FALSE) { # \dontrun{
df <- c(runif(n=30, min=0, max=1),rep(1,5))
breaks  <-  c(0, 0.249, 0.99, 1)

freq <- fn_freqw(df, breaks, right=FALSE)
} # }
