'descriptive' package
List of functions
This is a package for descriptive statistics, both univariate and multivariate. A list of available functions follow.
Functions for data manipulation:
- continuous_freq: frequencies for continuous data
- discrete_freq: frequencies for discrete data
- subsample: subsample extraction
- transform_sample: sample transformations
Univariate descriptive statistics:
- mean: sample mean
- smin: sample minimum value
- smax: sample maximum value
- range: the range
- noncentral_moment: non central moment
- central_moment: central moment
- var: variance (divided by n)
- std: standard deviation based on var
- var1: variance (divided by n-1)
- std1: standard deviation based on var1
- median: median
- quantile: p-quantile
- qrange: interquartilic range
- skewness: skewness coefficient
- kurtosis: kurtosis coefficient
- harmonic_mean: harmonic mean
- geometric_mean: geometric mean
- cv: variation coefficient
- mean_deviation: mean deviation
- median_deviation: median deviation
- pearson_skewness: Pearson's skewness coefficient
- quartile_skewness: quartilic skewness coefficient
Multivariate descriptive statistics:
- cov: covariance matrix (divided by n)
- cov1: covariance matrix (divided by n-1)
- cor: correlation matrix
- global_variances: gives a list with
- total variance
- mean variance
- generalized variance
- generalized standard deviation
- efective variance
- efective standard deviation
- list_correlations: gives a list with
- precision matrix
- multiple correlation coefficients

- principal_components
Statistical diagrams:
- scatterplot
- histogram
- barsplot
- boxplot
- piechart
- stemplot
- starplot
