My task is to model adoption of new technology A given the old technologies B and C. Suppose that C is universal to everyone. Based on this scenario, I assume that a certain proportion of individuals from B or C may choose to switch to new technology. Thus, there binary choice 0/1 for technology adoption. Which model can I use to determine how many will switch from each cohort to adopt??? Will it be correct to apply a Binomial/Beta Binomial distribution???
