Techniques For Feature Selection
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.
In this note, we will give the recursive formulas for sample mean and sample variance, and their generalized forms for batch updates.
In this note, we will analyze the variance of stepwise sample means (SSM).

Summer Internship 2024 at Hikma Pharmaceuticals USA Inc.
✈️ 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.
Performing Statistical Tests and Analysis in R
💻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🕐
