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.ellulitis 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.
