Robustness of Group Testing in the Estimation of Proportions

Biometrics, 1999
Summary. In binomial group testing, unlike one‐at‐a‐time testing, the test unit consists of a group of individuals, and each group is declared to be defective or nondefective. A defective group is one that is presumed to include one or more defective (e.g., infected, positive) individuals and a nondefective group to contain only nondefective ...

The Estimation of Proportions in m Groups

Psychometrika, 1973
In many applications, it is desirable to estimate binomial proportions in m groups where it is anticipated that these proportions are similar but not identical. Following a general approach due to Lindley, a Bayesian Model II aposteriori modal estimate is derived that estimates the inverse sine transform of each proportion by a weighted average of the ...

Simultaneous Estimation of Proportions in a Finite Population

Calcutta Statistical Association Bulletin, 1993
Sequential and multistage sampling strategies via simple random sampling without replacement, are proposed for simultaneously estimating several proportions in a finite population. Various asymptotic first-order properties are addressed, while some limited moderate sample performance have also been included. AMS (1980) Subject Classification: Primary

Bioinformatic Estimation of DNA Methylation and Hydroxymethylation Proportions

2021
Simultaneous measurement of 5-methylcytosine (5-mC) and 5-hydroxymethylcytosine (5-hmC) at the single-nucleotide level can be obtained by combining data from DNA processing methods including traditional bisulfite (BS), oxidative bisulfite (oxBS), or Tet-assisted (TAB) bisulfite conversion.

Pseudo-bayes estimation of multinomial proportions

Communications in Statistics - Theory and Methods, 1981
In the simultaneous estimation of multinomial proportions, two estimators are developed which incorporate prior means and a prior parameter which reflects the accuracy of the prior means. These estimators possess substantially smaller risk than the standard estimator in a region of the parameter space and are much more robust than the conjugate Bayes ...

Estimating the Proportion of Loyal Buyers

Journal of Marketing Research, 1964
Of the people who buy a brand or product in a given period of time, a certain number—the “loyal” buyers—will buy again in a later one. The proportion of buyers who are loyal in both can be predicted from a mathematical model, using observed data relating to one period only. In verifying the predictions against the actually observed loyalty proportion

Minimax Estimation of Proportions Under Random Sample Size

Journal of the American Statistical Association, 1995
Abstract We study the problem of how to estimate the parameters of a multivariate hypergeometric distribution when the sample size n is assumed to be an ancillary statistic. The minimax estimator for squared error loss is given. This estimator differs from the well-known minimax estimator for fixed n.

Construction of improved estimators of multinomial proportions

Communications in Statistics - Theory and Methods, 2000
The improved large sample estimation theory for the probabilities of multi¬nomial distribution is developed under uncertain prior information (UPI) that the true proportion is a known quantity. Several estimators based on pretest and the Stein-type shrinkage rules are constructed.
