Linear and logistic regression Factor analysis Factor analysis is a technique used to reduce a large number of variables into fewer factors. The factors are constructed in such a way that they capture the maximum possible information from the original variables. This technique is often used in mark...
Let’s see if there’s a linear relationship between income and happiness in our survey of 500 people with incomes ranging from $15k to $75k, where happiness is measured on a scale of 1 to 10. To perform a simple linear regression analysis and check the results, you need to run two ...
