The Continuous Case: Gaussian Bayesian Networks

In this chapter we will continue our exploration of BNs, focusing on modelling continuous data under a multivariate Normal (Gaussian) assumption.

2.1 Introductory Example: Crop Analysis

Suppose that we are interested in the analysis of a particular plant, which we will model in a very simplistic way by considering:

the potential of the plant and of the environment;
the production of vegetative mass;
and the harvested grain mass, which is called the crop.

To be more precise, we define two synthetic variables to describe the initial status of the plant: its genetic potential, which we will denote as G, and the environmental potential of the location and the season it is grown in, which ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
