Linear Regression Numerical Example with Multiple Independent Variables -Big Data Analytics Tutorial#BigDataAnalytics#RegessionSolvedExampleWebsite: www.vtup Se hela listan på guru99.com For example, we can use multiple regression to assess the relationship between the number of dengue cases in Malaysia with factors, such as urbanization, rainfall, temperature, age group of population and incidence by states.

regress is useful when you simply need the output arguments of the function and when you want to repeat fitting a model multiple times in a loop. If you need to investigate a fitted regression model further, create a linear regression model object LinearModel by using fitlm or stepwiselm. Such models are commonly referred to as multivariate regression models. Now let’s look at the real-time examples where multiple regression model fits.
