Your problem sounds like it could be modeled with logistic regression whereby the propensity for one result or another is "linked" to the factors that control it. Logistic regressions are a special case of generalized linear models. Look at ?glm

Subject: [R] bimodal data

    Hi,    

  Does anybody have a good tip of how to treat bimodal data to perform statistical analyses? My data set ranges from -1 to 1 (any values are posssible in between) and most data are either close to -1 or close to 1. They are the results of a two choice experiment where individuals could choose more than once in either direction and scores were calculated.
