Sample Size Calculation for Diagnostic Tests in Generalized Linear Mixed ModelsIntra-cluster correlations have to be taken into account for calculating the stochastic behaviour of estimators in diagnostic studies with repeated measurements on individuals. One approach of inducing the intra-cluster ...

Sample size calculation and sampling techniques For example, a company with decentralized records in multiple locations may need to sample locations first and then sample records within each of the sampled locations. New IRS guidance boosts statistical sampling We hoped to prove that in-store sampling...
摘要: A letter to the editor is presented in response to the article "Understanding the relevance of sample size calculation" by B. K. Nayak in a 2010 issue.关键词: Medicine(General Ophthalmology DOI: 10.4103/0301-4738.103809 被引量: 2 ...
Optimum sample size is an essential component of any research. The main purpose of the sample size calculation is to determine the number of samples needed to detect significant changes in clinical parameters, treatment effects or associations after data gathering. It is not uncommon for studies to...
