I am a marketer seeking modeling help. I would like to evaluate the impact of different programs on several types of company performance. Specifically, I want to know how marketing efforts and technical fixes are likely influencing website visits, conversion rates, and sales. Additionally, I would like to estimate how my individual employees and managers are likely impacting performance as I shift them around in their jobs and departments (hierarchical analysis). I need to be able to run these analyses continuously, preferably in R.
There are continuous, ordinal, and binary independent variables. Dependent variables are continuous.
