Synthesise Likert scale and related rating-scale data with predefined first and second moments (mean and standard deviation), and, optionally, correlate multiple vectors using a predefined correlation matrix. Additionally, generate synthetic rating-scale items with a predefined Cronbach's Alpha, or create rating-scale items based on a predefined summated scale.
