Web31 jul. 2024 · We used a hurdle regression model to examine whether organizational determinants, such as implementation climate and innovation-values fit, were associated with effective implementation. We defined effective implementation in two ways: implementation versus non-implementation and program reach (i.e., the proportion of the … Web6 jan. 2024 · ZINB regression model to over-dispersion count data caused by excess zero. However, the hurdle model is flexible and can handle under-dispersion, over-dispersion, and excess zeros problem. In particular, a hurdle model is mixed by a binary outcome of the count being below or above the hurdle.
