Description Usage Arguments Examples
Returns the hazard ratios at a selected time for specified scenarios of the threshold regression model.

object |
a thregI object. |
var |
specifies the categorical variable which is required for the hazard ratios. Transform this variable into factor variable that has been used in thregI(). The lower level of the factor variable of var is the reference level of hazard ratio. |
timevalue |
specifies the desired time at which the hazard ratios would like to be had. A vector is allowed for this argument. |
scenario |
specifies the values of all variables that considered in the thregI() except variable of var. |
