Descriptive Statistics

Description

desc_stat() function calculates various key descriptive statistics for each variables in the provided data set. The function computes the count, number of unique values, duplicate count, number of missing values, null rate, data type, minimum value, 25th percentile, mean, median, 75th percentile, maximum value, standard deviation, kurtosis, skewness, and jarque_pvalue for each variable.

Usage

desc_stat(
  data,
  count = TRUE,
  unique = TRUE,
  duplicate = TRUE,
  null = TRUE,
  null_rate = TRUE,
  type = TRUE,
  min = TRUE,
  p25 = TRUE,
  mean = TRUE,
  median = TRUE,
  p75 = TRUE,
  max = TRUE,
  sd = TRUE,
  skewness = FALSE,
  kurtosis = FALSE,
  shapiro = FALSE,
  kolmogorov = FALSE,
  anderson = FALSE,
  lilliefors = FALSE,
  jarque = FALSE
)
