Selection index theory is an important tool for animal breeders. This theory can be used for combining multiple sources of information to estimate breeding values. This ensures that the accuracy of estimated breeding value is optimized. This post outlines selection index theory in simple terms, gives some examples, and introduces …
Estimated breeding values (EBV) are an important resource for animal and plant breeders. The genetic improvement that has been realized in animal and plant breeding has been largely due to the use of estimated breeding values. These values play a pivotal role in genetic selection, driving improvements in populations over …
The Birthday Paradox is not a puzzle about birthdays per se, but rather a striking illustration of probability theory. It poses a question that seems counterintuitive at first: What is the chance that in a room of 23 people, at least two people share the same birthday? Have a guess …
Some problems in probability theory can seem difficult to solve. For example, have you ever wondered about the probability of something happening at least once? This problem may seem complex, because the number of possible scenarios that agree with this outcome is very large, and calculating each of their probabilities …
The Monty Hall problem is a classic probability puzzle based on a game show called Let’s Make a Deal. The problem is named after the show’s host, Monty Hall. The Monty Hall problem refers to a statistical puzzle that can seem very counter-intuitive. Imagine you participate in a television show, …
Regression to the mean is a statistical phenomenon that can be hard to grasp. In this post, I will give a simple explanation, with some intuitive and non-technical examples. Key message Regression to the mean (or shrinkage) is the phenomenon that occurs when extreme observations (or data points) tend to be …
