Increased sample size 2015 Survey of Doctorate Recipients first time reporting fine fields
2017/7/25
The National Science Foundation's National Center for Science and Engineering Statistics has more than doubled the sample size of its 2015 Survey of Doctorate Recipients in order to examine employment...
Estimating the sample size for fitting taper equations
sampling methods tree shape regression
2015/3/12
Much work has been done fitting taper equations to describe tree bole shapes, but few researchers have investigated how large the sample size should be. In this paper, a method that requires two varia...
Monotonicity in the Sample Size of the Length of Classical Confidence Intervals
Gamma function Location and scale parameters Stochastic monotonicity
2012/3/1
It is proved that the average length of standard confidence intervals for parameters of gamma and normal distributions monotonically decrease with the sample size. The proofs are based on fine propert...
Efficient adaptive designs with mid-course sample size adjustment in clinical trials
adaptive design conditional power futility Kullback-Leibler information sample size re-estimation
2011/6/17
Adaptive designs have been proposed for clinical trials in which the nuisance parameters
or alternative of interest are unknown or likely to be misspecified before the trial. Whereas most
previous w...
In several interesting applications one is faced with the problem of simultaneous binary hypothesis testing and parameter estimation. Although such joint problems are not infrequent, there exist no sy...

2009/9/22
This paper presents several new results on Bayesian sample size deter-
mination for estimating binomial proportions, and provides a comprehensive com-
parative overview of the subject. We investigat...

Sample size and positive false discovery rate control for multiple testing
Multiple hypothesis testing pFDR large deviations
2009/9/16
Positive false discovery rate (pFDR) is a useful overall measure of errors for multiple hypothesis testing, especially when the underlying goal is to attain one or more discoveries. Control of pFDR cr...
Understanding the role of text length, sample size and vocabulary size in determining text coverage
text coverage sample size text length vocabulary size standard deviation sampling methodology
2009/8/5
Although the use of "text coverage" to measure the intelligibility of reading materials is increasing in the field of vocabulary teaching and learning, to date there have been few studies which addres...
Asymptotic Results of a High Dimensional MANOVA Test and Power Comparison When the Dimension is Large Compared to the Sample Size
Hiroshima University
2009/3/9
This paper is concerned with Dempster trace criterion for multivariate linear hypothesis which was proposed for high dimensional situation. First we derive asymptotic null and nonnull distributions of...
Exact Computation of Minimum Sample size for Estimation of Poisson Parameters
Exact Computation Minimum Sample size Estimation Poisson Parameters
2010/4/30
In this paper, we develop an approach for the exact determination of the minimum sample
size for the estimation of a Poisson parameter with prescribed margin of error and confidence
level. The exact...

2010/4/30
It is a common contention that it is an “impossible mission” to exactly determine the
minimum sample size for the estimation of a binomial parameter with prescribed margin of
error and confidence le...
