A supervisor is looking to understand why some of their programs are not successful. They provide you a dataset containing the location, funding, date, duration, 5 program indicators, and target of their 15 programs, along with how successful they are on a scale of 1-5. They ask for a regression analysis to identify which of the factors are contributing most to the programs' success or failure. What would be your primary analytical concern? The sample size is too small Too few variables The temporal dimension is unclear Too many variables
