Addition of +1 to the denomenator

Hi!

We use a logistic regression here, right?

So, the addition of 1 to the denominator in the logistic function is essential for transforming the linear combination of input features into a probability. It ensures that the output is bounded between 0 and 1, making it suitable for probability estimation in tasks such as calculating the probability of default for a customer.

Hope this helps!

Best,

not clear we have (1-pd)/pd=12.21 and even if we add 1 to the denomenator the equation should be 1-pd/pd=13.21 ,where is pd from the denomenator is going as in the video the equation says 1-pd=13.21??
