StatQuest: Logistic Regression Transcript
Josh Starmer: Hello. I’m Josh Starmer and welcome to StatQuest. Today, we’re going to talk about logistic regression. This is a technique that can be used for traditional statistics, as well as machine learning. Let’s get right to it.
Before we dive into logistic regression, let’s take a step back and review linear regression. In another StatQuest, we talked about linear regression. We had some data, weight and size, then we fit a line to it and with that line, we could do a lot of things. First, we could calculate R squared and determine if weight and size are correlated. Large values imply a large effect. And second, calculate a p-value to determine if the R squared value is statistically significant. And third, we could use the line to predict size given weight. If a new mouse has this weight, then this is the size that we predict from the weight. Although we didn’t mention it at the time, using data to predict something falls under the category of machine learning. Plain old linear regression is a form of machine learning. We also talked a little bit about multiple regression. Now we are trying to predict size using weight and blood volume. Alternatively, we could say that we are trying to model size using weight and blood volume.
Multiple regression did the same things that normal regression did. We calculated R squared and we calculated the p-value and we could predict size using weight and blood volume. And this makes multiple regression a slightly fancier machine learning method. We also talked about how we can use discrete measurements like genotype to predict size. If you’re not familiar with the term genotype, don’t freak out. It’s no big deal. Just know that it refers to different types of mice.
Lastly, we could compare models. On the left side, we’ve got normal regression using weight to predict size and we can compare those predictions to the ones we to get from multiple regression, where we’re using weight and blood volume to predict size. Comparing the simple model to the complicated one tells us if we need to measure weight and blood volume to accurately predict size or if we can get away with just weight.
Now that we remember all the cool things we can do with linear regression, let’s talk about logistic regression. Logistic regression is similar to linear regression except logistic regression predicts whether something is true or false, instead of predicting something continuous like size. These mice are obese and these mice are not. Also, instead of fitting a line to the data, logistic regression fits an S shaped logistic function. The curve goes from zero to one and that means that the curve tells you the probability that a mouse is obese based on its weight. If we weighed a very heavy mouse, there’s a high probability that the new mouse is obese. If we weighed an intermediate mouse, then there’s only a 50% chance that the mouse is obese. Lastly, there’s only a small probability that a light mouse is obese.
Although logistic regression tells the probability that a mouse is obese or not, it’s usually used for classification. For example, if the probability a mouse is obese is greater than 50%, then we’ll classify it as obese, otherwise will as not obese. Just like with linear regression, we can make simple models. In this case, we can have obesity predicted by weight or more complicated models. In this case, obesity is predicted by weight and genotype. In this case, obesity is predicted by weight and genotype and age. And lastly, obesity is predicted by weight, genotype, age and astrological sign. In other words, just like linear regression, logistic regression can work with continuous data like weight and age and discreet data like genotype and astrological sign. We can also test to see if each variable is useful for predicting obesity. However, unlike normal regression, we can’t easily compare the complicated model to the simple model and we’ll talk more about why in a bit.
Instead, we just test to see if a variable’s effect on the prediction is significantly different from zero. If not, it means that the variable is not helping the prediction. We use Wald’s Test to figure this out. We’ll talk about that in another StatQuest. In this case, the astrological sign is totes useless. That’s statistical jargon for not helping. That means we can save time and space in our study by leaving it out. Logistic regression’s ability to provide probabilities and classify new samples using continuous and discreet measurements makes it a popular machine learning method.
One big difference between linear regression and logistic regression is how the line is fit to the data. With linear regression, we fit the line using least squares. In other words, we find the line that minimizes the sum of the squares of these residuals. We also use the residuals to calculate R squared and to compare simple models to complicated models. Logistic regression doesn’t have the same concept of a residual, so it can’t use least squares and it can’t calculate R squared. Instead it uses something called maximum likelihood.
There’s a whole StatQuest on maximum likelihood so see that for details but in a nutshell, you pick a probability scaled by weight of observing an obese mouse, just like this curve and you use that to calculate the likelihood of observing a non-obese mouse that weighs this much and then you calculate the likelihood of observing this mouse and you do that for all of the mice. And lastly, you multiply all of those likelihoods together. That’s the likelihood of the data given this line. Then you shift the line and calculate a new likelihood of the data and then shift the line and calculate the likelihood again. And again. Finally, the curve with the maximum value for the likelihood is selected. Bam!
In summary, logistic regression can be used to classify samples and it can use different types of data like size and or genotype to do that classification and it can also be used to assess what variables are useful for classifying samples, i.e. astrological sign is totes useless.
Hurray! We’ve made it to the end of another exciting StatQuest. If you like this StatQuest and want to see more, please subscribe. And if you have suggestions for future StatQuests, well, put them in the comments below. Until next time, quest on.
Week 11: Modeling Relationships
Introduction
Last week, you looked at relationships between variables measured at the interval level, called correlation. In health care, we often want to know if we can “predict” an outcome based on an intervention. This week, we will look at the predictive probability of an outcome occurring. However, we need to ensure that we have a correlation between variables measured on the interval level before we can use modeling relationships, called linear “regression”.
We can also use a regression technique using nominal and categorical variables. We term this logistic regression. Both linear regression and logistic regression fall under the category of statistical testing known as multivariate statistics.
