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 commonly occurs near breaks in the skin, such as surgical wounds, trauma, tinea infections (Figure 1), or ulcerations, but occasionally presents in skin that appears normal. Patients may have a fever and an elevated white blood cell count. Cellulitis can occur on any part of the body.
