Logistic Regression estimates the probability of binary outcome as a function of independent variables.


An example is the probability that a borrower will default as a function of his credit score,


income, loan size and his current debts. In other words, Logistic Regression is a statistical method


for analyzing dataset in which there are one or more independent variables (predictor) that determine


the outcome of a dichotomous dependent variable such as YES or NO. Dichotomous is an outcome variable


with the possibility of only two alternative outcomes such as TRUE or FALSE.


Binary logistic regression model is used to estimate the probability of the binary response of dependent


variable based on one or more independent or predictor variables. Logistic regression uses categorical


predictor to predict the binary dependent outcome.




In assessing the predictive power of categorical predictors of a binary outcome,


should logistic regression be used?




Another way to frame the question is:


Can logistic regression be used to predict


categorical outcome?


If yes, then how can logistic regression be used to predict


categorical outcome?


If no, why?


Start by defining Logistic regression


Define binary logistic regression.


Describe the predictive power of  categorical variable on binary outcome.
