Determination of the optimal sample size for a clinical trial accounting for the population size [PDF]

, 2017
The problem of choosing a sample size for a clinical trial is a very common one. In some settings, such as rare diseases or other small populations, the large sample sizes usually associated with the standard frequentist approach may be infeasible ...

ImpZ: a new photometric redshift code for galaxies and quasars [PDF]

, 2004
We present a combined galaxy-quasar approach to template-fitting photometric redshift techniques and show the method to be a powerful one. The code (ImpZ) is presented, developed and applied to two spectroscopic redshift catalogues, namely the Isaac ...

SAMPLE SIZE DETERMINATION FOR AGRONOMIC EXPERIMENTS

The Iraqi Journal of Agricultural science
Determining sample size to estimate the mean value of a target (infinite) population is of prime importance to have correct results and conclusions. In general, sample sizes differ as the studied objects differ.

Indicators of Evidence for Bioequivalence

Entropy, 2016
Some equivalence tests are based on two one-sided tests, where in many applications the test statistics are approximately normal. We define and find evidence for equivalence in Z-tests and then one- and two-sample binomial tests as well as for t-tests ...
