Data Preparation and Analysis: Master Python Data Analysis

Welcome to Data Preparation and Analysis! Module 1 guides students through the art of crafting informative and visually appealing histograms, a fundamental aspect of data visualization. Students will learn techniques for measuring the location and scale of data, understanding the origins and impacts of noise and missing values in datasets. This module also introduces the CRISP-DM Process, a structured approach to data mining, along with Gartner's Analytics Ascendancy Model for advanced data analysis.

Module 2 delves into the intricacies of statistical analysis, beginning with a thorough understanding of the p-value concept and its significance as a Type I Error indicator. Students will learn to apply statistical tests in Python to identify significantly correlated features, exploring various correlation metrics tailored for categorical, mixed-type, and continuous features.

Module 3 offers a deep dive into the world of Association Rules, teaching students how to improvise these rules for identifying valuable feature combinations that generate specific label values. Learners will master setting appropriate thresholds for Support and Confidence and gain a comprehensive understanding of the Apriori Algorithm and the significance of Frequent Itemsets within it.

In Module 4, students will learn how to describe and interpret profiles of clusters, gaining proficiency in deploying the K-Means and K-Modes clustering algorithms. They will explore the application of Recency, Frequency, and Monetary (RFM) Analysis to identify the most valuable customers in retail business settings.

This module delves into feature importance analysis in machine learning, covering Shapley Values, feature selection methods, statistical evaluation, feature interaction, aliasing, and the Least Squares Algorithm. Students will be able to master these concepts to build robust and interpretable models.

In Module 6, students will master the art of feature selection in machine learning by exploring the Forward and Backward Selection Method, the All-Possible Subsets Method, and the concept of complete and quasi-complete separation. Students will also discover association rules for identifying separations, interpret model parameters and predicted probabilities.

Module 7 will equip students wth the ability to harness the power of tree-based models to uncover hidden patterns in your data. Students will be able to describe clusters effectively, intelligently set algorithm parameters, construct business rules from tree results, and utilize variance metrics, entropy values, and Gini indices for optimal tree construction.

Module 8 delves into the realm of evaluation metrics for machine learning models. Students will master the concepts of precision and recall curves, lift curves, and receiver operating characteristics (ROC) curves. Additionally, students will obtain the ability to discover methods for calculating probability thresholds using Kolmogorov-Smirnov statistics and F1 scores.

This module contains the summative course assessment that has been designed to evaluate your understanding of the course material and assess your ability to apply the knowledge you have acquired throughout the course.
