On two-stage parameter estimation in static system
IEEE Transactions on Systems, Man, and Cybernetics, 1983The general two-stage estimation idea is described. Maximum likelihood and maximum a posteriori probability methods for two-stage estimation are presented. The estimation algorithms for simple cases are given. The comparison of the direct and two-stage estimation is discussed.

Estimation in flexible two stage designs
Statistics in Medicine, 2006Adaptive test designs for clinical trials allow for a wide range of data driven design adaptations using all information gathered until an interim analysis. The basic principle is to use a test statistics which is invariant with respect to the design adaptations under the null hypothesis.

On a Two-Stage Estimate of the Mean
Journal of the American Statistical Association, 1971Abstract A two-stage estimate for the mean vector of a multivariate distribution is proposed for the situation in which the prior knowledge about the mean vector can be expressed in the form of an initial estimate. The proposed estimate is compared with the sample mean based on a single sample of equivalent size.

A Two‐Stage Stepwise Estimation Procedure
Biometrics, 2008Summary This article proposes a two‐stage simultaneous confidence procedure for the comparisons of k pairs of population means, without using multiplicity adjustment of more than two populations. The proposed procedure can be broadly applied to parametric or nonparametric models.

TSGYE: Two-Stage Grape Yield Estimation
2020Vision-based grape yield estimation provides a cost-effective solution for intelligent orchards. However, unstructured background, occlusion and dense berries make it challenging for grape yield estimation. We propose an efficient two-stage pipeline TSGYE: precise detection of grape clusters and efficient counting of grape berries.
