Correlation Analysis:

A statistical technique used to measure the linear relationship between two or more rating or ratio-scaled variables (continuous variables)

2

Hypothesis Test

 Focus on the slope
- Ho: There is no relationship between sales and price
(βprice=0)
- Ha: There is a relationship between sales and price
(βprice≠0)
 What does the p-value tell us?

3

Multiple Regression Analysis

Y=β0 +β1X1 +β2 X2 +β3 X3
 Multiple independent variables
 Interpretation of regression coefficients

4

When to use Logistic Regression?

Logistic regression “...is similar to a linear regression model but is suited to models where the dependent variable is discrete/categorical”.

5

Method to use for continuous



Linear Regression (just covered in our class)

6

Method to use for Discrete (dichotomous)

Logistic Regression (Binary Logistic)

7

Method to use for Discrete (multichotomous)

Logistic Regression (multinomial Logistic)
