ESTYP: Extended Statistical Toolkit Yet Practical

Description

ESTYP (Extended Statistical Toolkit Yet Practical) is a Python library that serves as a multifaceted toolkit for statistical analysis. The testing module encompasses a wide range of statistical tests, including t-tests, chi-squared tests, and correlation tests, providing robust methods for data comparison and validation. In the linear_model module, users can find functionalities related to logistic regression, including variable selection techniques and additional methods for calculating confidence intervals and p-values. This module enhances the capabilities of traditional logistic regression analysis. The cluster module is designed to assist in clustering analysis, offering tools to identify the optimal number of clusters using methods like the elbow or silhouette techniques. Together, these modules form a comprehensive and practical statistical toolkit that caters to various analytical needs.

Actually, the name comes from the way my friends call me (Esti), plus "p" which is the initial of python.

Features

testing module

• testing.CheckModel(): This class provides methods to test the assumptions of the linear regression model., inspired by the performance::check_model() function of the R software.
• testing.t_test(): Performs one and two sample t-tests on groups of data. This function is inspired by the t.test() function of the R software.
• testing.var_test(): Performs an F test to compare the variances of two samples from normal populations. This function is inspired by the var.test() function of the R software.
• testing.prop_test(): it can be used for testing the null that the proportions (probabilities of success) in several groups are the same, or that they equal certain given values. This function is inspired by the prop.test() function of the R software.
• testing.chisq_test(): Performs a chi-squared test of independence of variables in a contingency table. This function is inspired by the chisq.test() function of the R software.
• testing.cor_test(): Performs a correlation test with Pearson, Spearman or Kendall method. This function is inspired by the cor.test() function of the R software.
• testing.nested_models_test(): Performs a nested models test to compare two nested models using deviance criterion.

linear_model module

• linear_model.LogisticRegression(): This class implements a logistic regression model. It inherits from the LogisticRegression() class from scikit-learn, but adds additional methods for calculating confidence intervals, p-values, and model summaries like Logit class in statsmodels.
• linear_model.stepwise.both_selection(): This function performs both forward and backward variable selection using the Akaike Information Criterion (AIC).
• linear_model.stepwise.forward_selection(): This function performs forward variable selection based on p-values.

cluster module

• cluster.NClusterSearch: A helper class to identify the optimal number of clusters for clustering algorithms with elbow or silhuette methods.
