if a subpopulation is different from the whole population, how are the expected voi and the estimated voi related in the model does the sum of the subpopulation model include the total variable what is the difference between estimated voi and voi what is meant by voi how to find the variable of interest for a population a variable of interest is a measure of the voi meaning how to calculate subpopulations and their variable of interest in a population how to find the variable of interest in a subpopulation what is the voi? how to calculate vai in population which variable is not equal to the predicted variable of interest? which factor is used to calculate voi how to figure voi why is the expected voi different from the total which is the best way to estimate the variable of interest across the entire population? what's the relationship between voi and estimates how to predict the variable of interest how do i predict variable of interest what makes up an estimated voi?
