SMALL SAMPLE SIZE IN 2X2 CROSS OVER DESIGNS: CONDITIONS OF DETERMINATION
Introduction. Determination of small sample size in some clinical trials is a matter of importance. In cross-over studies which are one types of clinical trials, the matter is more significant.

Preliminary Proactive Sample Size Determination for Confirmatory Factor Analysis Models [PDF]
Proactive preliminary minimum sample size determination can be useful for the early planning stages of a latent variable modeling study to set a realistic scope, long before the model and population are finalized. This study examined existing methods and

Sample Size Determination [PDF]
Scientists who use animals in research must justify the number of animals to be used, and committees that review proposals to use animals in research must review this justification to ensure the appropriateness of the number of animals to be used.

Scientific Research Sample Size Determination
Determining the appropriate sample size is an essential factor for an empirical study. A sample size that is too small will not yield valid results or adequately represent the reality of the population under study.

Tolerance Limits and Sample-Size Determination Using Weibull Trimmed Data
Guaranteed-coverage and expected-coverage tolerance limits for Weibull models are derived when, owing to restrictions on data collection, experimental difficulties, the presence of outliers, or some other extraordinary reasons, certain proportions of the
