## Errors of Predictive Models

You’ve created a bunch of predictive models and you need to measure the accuracies of each of them to choose the one that’s best for your purposes.

In this course I’m going to show you all of the most used measures and teach you exactly when to use them – and when not to.

Most importantly I’m going to show you how to interpret each of them, so you always know which is the best measure for your uses.

So you’ve created a bunch of predictive models and now you need to choose the one that’s best for your purposes.

How do you do this? Eeny meeny? Throw darts at them?

Probably not.

You need to be able to measure the accuracies of each of your models so you can choose between them *objectively*.

The only problem is that there are literally *loads* of different measures you can use. Reading around the internet and watching videos on YouTube will only make you more confused, because each method has its own set of dedicated fans.

In this course I’m going to show you all of the most used measures and show you exactly when to use them and – more importantly – when not to.

And there’s only one place in the universe that you can get this course – **right here!**

**If you’re truly interested in measuring the effectiveness of your models, don’t miss this course!**

#### Here's what you'll learn:

**1.**

you’ll learn why most papers textbooks and articles get the terminology wrong – and how to get it right

**2.**

you’ll learn how to calculate the errors of regression-based predictive models – with lots of practice sessions

**3.**

you’ll learn how to calculate the errors of classification-based predictive models –lots more practice sessions

**4.**

you’ll learn exactly which statistical tests to use, why, when and how – and how to interpret them correctly too!
