How much can the owner of a CPA firm make? I'm planning to get the CPA license and start my own small CPA firm. I want to hire bookkeepers and outsource the work overseas to save on overhead costs. I already have a large family of about 80 people, so I believe I can make at least 100 clients in my first year and do their taxes.
Answer Wiki. There are no independent variables in observational studies. In an observational study, the researcher compares subjects against a control group and comes to a conclusion. Hypothetical example: if we have a research study comparing the risk of developing liver cancer between (1) people who drink some alcohol daily, and (2) teetotalers.
An interaction variable is a variable constructed from an original set of variables to try to represent either all of the interaction present or some part of it. In exploratory statistical analyses it is common to use products of original variables as the basis of testing whether interaction is present with the possibility of substituting other more realistic interaction variables at a later stage.
