## Description

In almost all areas of life, large amounts of data are generated, requiring dedicated procedures for data analysis to allow predictions and inference for decision making. Computational statistical methods have evolved to cope with challenges arising from large datasets that are not tractable with traditional approaches, e.g. when the number of possible parameters of a model exceeds the number of observations. At the same time, this wealth of data allows replacing distributional assumptions with data-driven analyses.

In this course, we will cover statistical summary of data, hypothesis testing, regression as well as statistical learning approaches with focus on clustering and classification. We will contrast traditional frequentist approaches for these tasks with non-parametric, computational more intensive alternatives and Bayesian approaches.

The lecture will be accompanied by regularly scheduled exercises, which focus on applying the covered method to real-life data from different areas of life. In the course we will work with R / Python. Basic programming knowledge is a prerequisite to successfully complete the exercises. For those students who are not familiar with any of these two languages, an introduction to R will be provided.

Learning Objectives:

• Understand concepts and methods of computational statistics
• Ability to statistically evaluate real-world data
• Ability to assess the quality and validity of a statistical method for a given analysis
• Ability to select, implement and apply appropriate statistical methods and algorithms for a given use case

## Requirements

• Fundamentals in calculus and vector analysis (at least comparable to the Mathematik I + II lectures in the ITSE Bachelor at HPI)
• Basic programming knowledge (Python or R are a plus)
• Knowledge of English (The lecture will be given in English, but you can ask questions in German and submit German solutions etc.)

## Learning

Exercises will be included into the lecture times when suitable.

Lectures / Exercises will be given in zoom with interactive elements including online quizzes and questions/chats. Call-In details will be provided in time.

­­­­­Due to the COVID-19 pandemic, this course will be offered online. Depending on the development of the pandemic, we will return to the lecture hall (if possible).

It is important that all participants enroll by April 12 via our Moodle page.

## Examination

Final exam covering all lecture materials (70% of final grade)
