Logistic regression mainly used for Regression

• True

• False

What are odds?

• It is the ratio of the probability of an event occurring to the probability of the event not occurring.

• It is the ratio of the probability of an event occurring to the probability of the sum of all events.

• It is the ratio of the probability of an event not occurring to the probability of the event occurring.

• It is the ratio of the probability of an event not occurring to the probability of the event not occurring.

Suppose you have been given a fair coin and you want to find out the odds of getting heads. Which of the following option is true for such a case?

• odds will be 0

• odds will be 0.5

• odds will be 1

• None of these

What is true in a Logistic Model?

• It has a bell-shape graph and its values ranges from -1 to 1

• It has a narrow bell-shape graph and its values ranges from -2 to 2

• It has an s-shape and its values ranges from 0 to 1

• It has parabolic-shape graph and its values ranges from 0 to 2

A logistic regression has the same assumptions as the linear regression except for?

• Nonlinearity

• Linearity

• Autocorrelation

• Homoscedasticity
