## How to analyze regression data?

Linear models are the most common and most straightforward to use. …If the dependent variable is continuous and your model has collinearity or a lot of independent variables, you can try, for example, ridge or lasso models. …If you are working with categorical data, you can try poisson, quasi-poisson and negative binomial regression.More items…

Regression testing in agile helps in identifying the problematic areas at an early stage so that the developers can immediately replace that section with proper code, It also advantages and disadvantages of regression analysis helps achieve better software reliability. As regression testing executes the same steps repeatedly and allows the team with shorter sprints to deliver better quality products to the customer.

## When should I use regression analysis?

Use regression analysis to describe the relationships between a set of independent variables and the dependent variable. Regression analysis produces a regression equation where the coefficients represent the relationship between each independent variable and the dependent variable. You can also use the equation to make predictions. As a statistician, I should probably tell you that I love all …
