In simple linear regression a single independent variable is used to predict the value of a dependent variable. In multiple linear regression two or more independent variables are used to predict the value of a dependent variable. The difference between the two is the number of independent variables.
Watching for Systemic Symptoms. 1  1. Watch from swollen glands. Serious cases of cellulitis will spread beyond the initially infected region to become systemic and impact the rest of the body. 2  2. Notice if you experience fever and/or chills.
Cellulitis most commonly develops on the legs but may occur anywhere. Cellulitis usually only affects one side of the body, such as one hand or one leg. The first symptoms of cellulitis are redness, pain, and tenderness over an area of skin. These symptoms are caused both by the bacteria themselves and by the bodyâs attempts to fight the infection.
