Exploratory Data Analysis, Group Comparison Tools, and Other Procedures

Provides a comprehensive set of tools for descriptive statistics, graphical data exploration, outlier detection, homoscedasticity testing, and multiple comparison procedures. Includes manual implementations of Levene's test, Bartlett's test, and the Fligner-Killeen test, as well as post hoc comparison methods such as Tukey, Scheffé, Games-Howell, Brunner-Munzel, and others. This version introduces two new procedures: the Jonckheere-Terpstra trend test and the Jarque-Bera test with Glinskiy's (2024) correction. Designed for use in teaching, applied statistical analysis, and reproducible research. Additionally you can find a post hoc Test Planner, which helps you to make a decision on which procedure is most suitable.

Analitica

Analitica is an R package that provides tools for descriptive statistics, exploratory visualization, outlier detection, homogeneity of variance tests, and post hoc group comparisons—both parametric and non-parametric.

It is especially useful for applied analysis, teaching, and reproducible research.

📦 Installation

You can install the development version from GitHub:

# install.packages("devtools")
devtools::install_github("<your_github_username>/Analitica")

✨ Features

• descripYG(): Descriptive summaries with histograms, boxplots, or ridge plots
• Levene.Test(), BartlettTest(), FKTest(): Homoscedasticity tests
• grubbs_outliers(): Univariate outlier detection using Grubbs' test
• GHTest(), TukeyTest(), ScheffeTest(), SNKTest(): Parametric post hoc tests
• MWTest(), BMTest(), BMTest_perm(): Non-parametric group comparisons

📊 Example

library(Analitica)
data(d_e, package = "Analitica")

descripYG(d_e, vd = Sueldo_actual, vi = labor)

mod <- aov(Sueldo_actual ~ as.factor(labor), data = d_e)
resultado <- GHTest(mod)
summary(resultado)
plot(resultado)
