Investigation on voice handicap index
Abstract: The client's objective is to find important factors causing the patients' voice
handicap and to investigate the influence of those factors. There are several
potential factors of interest: Diagnosis (kind of disease), Gender, Ethnicity,
voice therapy (whether the patient complies with doctors ~ R order or not), Age,
and Singer or not. All the explanatory factors are categorical variables. We run
PROC GLM in SAS and fit an ANOVA model with interactions between the factors.
The following factors are found significant in the data analysis: Diagnosis,
Singer, Therapy, Gender, and Gender*Diagnosis.
