what is model of multihurdle can multiple hurdle model be used what is the model that can use two different predictors which predictor should be used in multiple-hurdle does a mhurdle have two predictors when predicting a variable, what is the difference between a tobit and a multihurdle? what is mhurdle model of sss what kind of model is used to determine if a variable is zero what would you use for a multi-hurdle what is the difference between a model with two predictors and a model with two hurdles can you use a tobit model for multiple hurdles what model uses the same predictors for two hurdles and their relative effects? how to use multiple hurdle model when you use multiple hurdles model, what is the difference between a tobit and a tobit model? can a tobit model have two predictors why use a multiple hurdle model? what is the difference between a tobit and a multiple hurdle model what is the difference in tobit and mhurdle model how many predictors in multiple hurdle model what model use the same predictors as mhurdle
