Introduction to Logistic Regression
We use logistic regression to model binary response
variables
i.e. (0,1) variables
Examples:
gender (male, female)
AIDS test (positive, negative)

Recap from Week 9
Last week we learnt how to use moving averages to
deal with autocorrelation in time-series
We used them to de-seasonalise the time-series
Then we fitted a linear mo

Modelling Strategies
So far we have looked at the main effects of
explanatory variables on the response variable
Today we are going to look at strategies to model
more nuanced effects

Model Selection
In Week 4 we learnt that the best model is that which
maximises its capacity to explain the response variable without
compromising its simplicity

Motivation for Multiple Linear Regression
Last week we saw simple linear regression, a linear
model where we only include one explanatory variable
The great advantage of multiple linea
