Demo on the capability of Yandex CatBoost gradient boosting classifier on a fictitious IBM HR dataset obtained from Kaggle. Data exploration, cleaning, preprocessing and model tuning are performed on the dataset

Implementation of Lo and MacKinlay's statistical tests from A Non Random Walk Down Wall Street

Gene Set Enrichment Class Analysis for heterogeneous RNA sequencing data

GAUSS implementation of ICSS from Sansó et al. "Testing for Changes in the Unconditional Variance of Financial Time Series"

This is the repo for the project in Combinatorial Decision Making and Optimization at @unibo: optimizing a stock portofolio by using linear and quadratic optimization functions.

Hamming Network implementation using pca implementation for reduction all from scratch

In this note, we will give the recursive formulas for sample mean and sample variance, and their generalized forms for batch updates.

The Chinook Data Analysis Project leverages PostgreSQL, Python, and Google Spreadsheets to explore and analyze the Chinook music store database. Insights will be presented through Tableau Dashboards and Stories. Stay tuned for updates as the project evolves.

Techniques For Feature Selection

In this note, we will analyze the variance of stepwise sample means (SSM).

Performing Statistical Tests and Analysis in R

projeto de calculadora capaz de fazer o calculo de: variância, desvio padrão, Fibonacci, logaritmos e fatorial além das operações básicas

💻Anomaly detection can be 👨‍💻treated as a statistical📉 task as an outlier analysis📊. But if we develop a machine learning model📈, it can be automated and as usual, can save a lot of time🕐

Hamming Network implementation using PCA implementation from scratch

📗 This repository contains the EDA of loan defaulters, analyzing factors like loan type, ROI, and credit scores. It utilizes Random Forest and XGBoost to clean discrepancies, providing insights to enhance risk assessment and inform lending strategies, making it ideal for financial analysts to mitigate loan default risks.

✈️ Variance analysis of flight delays to conclude which one of the biggest airline companies in Brazil is the best

This repository contains a Python implementation of Principal Component Analysis (PCA) for dimensionality reduction and variance analysis. PCA is a powerful statistical technique used to identify patterns in data by transforming it into a set of orthogonal (uncorrelated) components, ranked by the amount of variance they explain.
