We begin with a little intro to the course as well as some general info on how the course is organized.
A few words about your humble teacher
Here, I will show you what to do if a blurry image appears
Here, I will show you how to find additional resources attached to the course, like Excel files, presentations, links, etc.
In this section, we will discuss the essential concepts that we will use to build and interpret linear regression models. You will also learn how to build a regression model in Excel.
In short, a function is a transformation of ingredients into output. It shows how much of every ingredient we should take to achieve the result.
In many situations, we want to predict the value of certain variables. This will help you optimize your business and prepare for the uncertain future.
Linear Functions are the easiest and most often used functions in Business. Let’s look at some examples to remind ourselves what they look like.
We know what a regression is and what linear functions are. Now, let’s combine them to get to the Linear Regression.
Some of the models that you will build using linear regression will not be a good tool for predicting the output. Let’s see how you can check that the model is ok.
Let's see how we can create a regression in Excel
Let’s imagine that you were asked to create a model that will forecast the sales of new convenience stores.
In this lecture, I will show you how to solve the case shown in the previous lectures.

In this lecture, I will show you how to solve the case shown in the previous lectures.
Let's look at the definition of correlation
It is a measure that helps check how 2 variables are related and whether they behave in the same way.
Correlation also tests the strength of the movement. The higher the absolute value of the correlation, the stronger the similarity in behavior
We can check whether things behave in the same way, but we cannot check whether they influence each other and what the direction of the influence is
We use the so-called Pearson correlation coefficient to measure the correlation
Now, let’s try to analyze the results from the correlation analysis for the service time for the restaurant chain.
In this lecture, we will solve the case study that we have introduced.
In this lecture, we will solve the case study that we have introduced.
Let’s see how we can find the potential input variables that are worth including in the model that will help us predict the output.
Let's have a look at different types of data that you will use.
Dummy variables are great because they help us use the information from variables that are categories in the regression model.
Let’s go back to our case study with convenience stores. We will try to translate the categories into dummy variables.
In this lecture, I will show you how to solve the case shown in the previous lectures.
In this lecture, I will show you how to solve the case shown in the previous lectures.
In this lecture, I will show you how to solve the case shown in the previous lectures.
Now, let’s discuss an important concept that will help you check whether your model is the right one or not. You will need the so-called residuals for that.
In this lecture, I will show you how to solve the case shown in the previous lectures.
This course contains the use of artificial intelligence.
What is the aim of this course?
During some consulting projects, you may be asked to predict things like sales or the number of customers. You may also be asked to find the relations between different variables and estimate their impact on a specific goal. In such situations, you may use linear regression models. They may prove extremely helpful in projects requiring data analysis and forecasting. In this course, I will teach you how to use essential linear regression models in Excel during consulting projects.
In the course, you will learn the following things:
What are linear regression models, and how can you use them in practice
This course is based on my 15 years of experience as a consultant in top consulting firms and as a Board Member responsible for strategy, performance improvement, and turn-arounds in the biggest firms from the Retail, FMCG, SMG, B2B, and services sectors that I worked for. I have carried out or supervised over 100 different performance improvement projects in different industries that generated a total of 2 billion additional EBITDA. On the basis of what you will find in this course, I have trained in person over 100 consultants, business analysts, and managers who are now Partners in PE and VC funds, Investment Directors and Business Analysts in PE and VC, Operational Directors, COO, CRO, CEO, Directors in Consulting Companies, Board Members, etc. On top of that, my courses on Udemy were already taken by more than 350 000 students, including people working in EY, McKinsey, Walmart, Booz Allen Hamilton, Adidas, Naspers, Alvarez & Marsal, PwC, Dell, Walgreens, Orange, and many others.
I teach through case studies, so you will have a lot of lectures showing examples of analyses and tools that we use. To every lecture, you will find attached (in additional resources) the Excel files as well as additional presentations, materials shown in the lectures, so as a part of this course, you will also get a library of ready-made analyses that can, with certain modifications, be applied by you or your team in your work.
Why have I decided to create this course?
During many consulting projects, you have to analyze data to find the link between different variables and do simple forecasting. Most firms don’t give you the full toolbox that you need to do that. This may lead to huge frustration during consulting projects and a lot of inefficiencies.
Therefore, I have decided to create this course that will help students understand and apply linear regression models. The course will give you the knowledge and insight into real-life case studies that will make your life during a consulting project much easier. Thanks to this course, you will know what and how to do during consulting projects. You will master how to analyze data and draw conclusions from the analyses. On top of that, you will also see how you can fix the most often occurring problems in linear regression models.
To sum it up, I believe that if you want to become a world-class Management Consultant or Business Analyst, you have to have a pretty decent understanding of linear regression models. That is why I highly recommend this course to Management Consultants or Business Analysts, especially those who did not finish business school. The course will help you become an expert in linear regression models at the level of McKinsey, BCG, Bain, and other top consulting firms.
In what way will you benefit from this course?
The course is a practical, step-by-step guide loaded with tons of analyses, tricks, and hints that will significantly improve the speed with which you understand and analyze businesses. There is little theory – mainly examples, a lot of tips from my own experience, as well as other notable examples worth mentioning. Our intention is that, thanks to the course, you will learn:
What are linear regression models, and how can you use them in practice
How to create a linear regression model in Excel
How to use them for forecasting
How to identify potential problems that may occur in the model
How to fix the problems
You can also ask me any questions either through the discussion field or by messaging me directly.
How is the course organized?
The course is currently divided into the following sections:
Introduction. We begin with a little introduction to the course, as well as some general info on how the course is organized
Essential concepts. In this section, we will discuss the essential concepts that we will use to build and interpret linear regression models. You will also learn how to build a regression model in Excel.
Potential Problems. In this section, we will discuss potential problems that may occur when you use regression models. Linear Regression only works when certain assumptions are met. If one of those assumptions is not met, your model may give you distorted estimations. That’s why in the section devoted to potential problems, we will discuss the assumptions, how to check them in practice, and what to do if they are not met.
Case Studies. In the last section, we will go through a series of case studies that will help you master how to use linear regression models in practice.
You will also be able to download many additional resources
1. Useful frameworks and techniques
2. Analyses shown in the course
3. Additional resources
4. Links to additional presentations, articles, and movies
