Dickinson_design: Raw county-level variables for study 1 in Dickinson et al...

Description Format Source References

Description

Two approaches (interventions) are compared for increasing the "up-to-date" immunization rate in 19- to 35-month-old children. 16 counties in Colorado 1:1 are randomized to either a population-based approach or a practice-based approach. Ahead of randomization, several county-level variables are collected, and a subset of them are used for covariate constrained randomization. The continuous variable of average income is categorized to illustrate the use of cvcrand on multi-category variables. And the percentage in CIIS variable is truncated at 100
