Question

1. The dependent variable has a score in the case of logistic regression. TRUE or FALSE and why?

2, If the probability of an even A is 0.2 and that of an event B is 0.10 then the odds ratio is: a.1 b. 2.25 c. 2.0 d. 0.5

3. In the case of logistic regression, we estimate how much the natural logarithm of the odds for Y =1 changes for a unit change in X. TRUE or FALSE

4. In binomial logistic regression, the dependent variables consists of more than two categories. TRUE or FALSE and why?

5. Similar to linear regression, logistic regression has one or more independent variables. TRUE or FALSE and why?

Answer 1

Dear student please rate me postive :)

Here is your solution -

Answer -1

The given statement is true

Because

In predictive analysis Logistic regression is used to predict in binary form i.e Yes or No thus the dependent variable takes binary scores such as 0-1.

Answer -2

Odds ratio is given by = [P(A)/(1-P(A)]/[P(B)/(1-P(B)]

= [0.2/(1-0.2)]/[0.1/(1-0.1)]

= 2.25

So option b is correct

Answer -3

This statement is true

because

Logistic regression is logit model in which logarithm of odds is function of unit x and the cofficient is the amount log odss changes with one unit change in X

Answer -4

The statement is false

Because in this

The dependent variable consists of two categories.

Answer -5

This statement is true

because

The independent variables in logistic regression model can be one or more binary or continuous variables but the dependent variable is binary in general ,It is modeled this way .
