Executive Development Programme in Handling Missing Data in Practical Scenarios

This course is designed for data analysts, data scientists, and business leaders who must handle missing data in practical scenarios. Participants will gain proficiency in identifying types of missing data, applying appropriate imputation techniques, and evaluating the impact of missing data on analysis outcomes.

Attendees will learn to use Python and R for data manipulation and analysis, develop a robust data cleaning workflow, and make informed decisions based on data integrity. Real-world case studies will provide practical insights into managing missing data in various industries, ensuring participants can apply their skills effectively in their professional roles.

1. 1. Introduction to Missing Data: Learners will understand the definitions, types, and causes of missing data and its impact on statistical analysis. They will gain foundational knowledge to identify and assess missing data issues in practical scenarios.
2. 2. Handling Missing Data Mechanisms: Learners will study the three missing data mechanisms (Missing Completely At Random, Missing At Random, and Missing Not At Random) and their implications. They will learn to recognize these mechanisms in real-world datasets and apply appropriate strategies to address them.
3. 3. Data Imputation Techniques: Learners will explore various imputation methods such as mean imputation, regression imputation, and multiple imputation. They will practice using these techniques in practical scenarios to handle missing values and improve data integrity.
4. 4. Advanced Imputation Methods: This module covers advanced imputation techniques like multiple imputation by chained equations (MICE) and machine learning-based imputation. Learners will apply these methods to complex datasets and evaluate their effectiveness.
5. 5. Dealing with Non-Response Bias: Focuses on understanding and mitigating non-response bias through the use of weighting, inverse probability weighting, and other advanced techniques. Learners will learn to adjust for non-response bias in survey data and other observational studies.
6. 6. Data Reduction and Feature Engineering: Learners will study how to reduce data dimensions and engineer new features to manage missing data more effectively. They will practice these skills in scenarios involving high-dimensional datasets and complex variable relationships.
7. 7. Handling Missing Data in Time Series: This module covers specific techniques for managing missing data in time series analysis, including interpolation, forecasting-based imputation, and state-space modeling. Learners will apply these methods to time series data to ensure accurate forecasting and analysis.
8. 8. Missing Data in Big Data Environments: Focuses on handling missing data in big data contexts, including the use of distributed computing frameworks and scalable imputation methods. Learners will gain skills in managing large-scale datasets with missing values efficiently.
9. 9. Validation and Evaluation of Imputation Methods: Learners will learn to validate and evaluate the performance of different imputation methods using metrics such as mean squared error and bias. They will apply these evaluation techniques to assess the quality of imputed data in various scenarios.
10. 10. Best Practices and Case Studies: This module provides an overview of best practices for handling missing data, including data documentation, transparency in reporting, and ethical considerations. Through case studies, learners will see how to apply these best practices in real-world scenarios.
