Two Stage Small Area Estimation [PDF]
Korean Journal of Applied Statistics, 2012 When Binomial data are obtained, logit and logit mixed models are commonly used for small area estimation. Those models are known to have good statistical properties through the use of unit level information; however, data should be obtained as area level in order to use area level information such as spatial correlation or auto-correlation.
