The Zero-Inflated ordered probit approach to modelling sports participation

► The paper explores the determinants of the frequency and the probability of sports participation. ► The Zero-Inflated Ordered Probit (ZIOP) model is applied. ► The ZIOP model allows accounting for excessive zero observations. ► It distinguishes between genuine 'non-participants' and the ones who do not participate at a time. ► The decision to take part and the frequency of sports participation are driven by separate factors.
