My dependent variable is an index from annual reports of companies (ranging from 0 to 1). The independent variables will be measured with Likert scales (individuals in each company will respond to the questions – a group of items rated with a Likert scale). What is the most appropriate statistic to use in this scenario? I need help please.
Dependent variable (index from one company) $=f$(Three separate Likert Scales measuring three different issues)
