This video describes how to do Logistic Regression in R, step-by-step. We start by importing a dataset and cleaning it up, then we perform logistic regression on a very simple model, followed by a fancy model. Lastly we draw a graph of the predicted probabilities that came from the Logistic Regression.
The code that I use in this video can be found on the StatQuest GitHub:

Paul Andersen explains how populations eventually reach a carrying capacity in logistic growth. He begins with a brief discussion of population size ( N ), growth rate ( r ) and exponential growth. He then explains how density dependent limiting factors eventually decrease the growth rate until a population reaches a carrying capacity ( K ). A mathematical simulation of this process is included along with a brief discussion of r and K selected species.

Logistics is an element of the overall supply chain, but specifically refers to the set of processes involved in moving raw materials and finished goods from Point A to Point B. Logistics includes transportation and warehousing processes like: receiving, inventory management, demand planning, picking, packing and shipping, transportation management, and order fulfillment.

Modern logistics! It would be hard to imagine our daily digital lives without them. As consumers, we can shop online every day and any hour of the day. We expect everything to arrive on time โ whether clothing, printer spare parts or a set of screws. Online shopping is booming: in 2018, courier, express and parcel services, the so-called CEP sector, delivered around 3.5 billion shipments in Germany alone. And this is an upward trend. But how does all this work so smoothly, safely and on time?
After all, we live in turbulent times: digitalization, climate crisis, growing world population and political and economic instability. How does the logistics industry rise to such challenges? For answers to these questions we need to dive deep into the world of modern logistics. Our film takes us into huge, fully connected warehouses, watching as fleets of cargo planes are prepared for take-off at night and accompanying couriers on delivery bikes on “the last mile” to the customer. We look at one of the world’s largest logistics providers at work: Deutsche Post DHL Group. We are more looking into solutions of robotization, working together with human workers within the warehouse on one hand. But also artificial intelligence and big data crunching is getting more and more important.
