Implicit pseudoreplication occurs when standard errors (or confidence limits) are estimated within experimental units. As with other sources of pseudoreplication, treatment effects cannot be statistically separated from effects due to variation among experimental units.
In engineering, science, and statistics, replication is the process of repeating a study or experiment under the same or similar conditions. It is a crucial step to test the original claim and confirm or reject the accuracy of results as well as for identifying and correcting the flaws in the original experiment. [1]
Reproducibility, closely related to replicability and repeatability, is a major principle underpinning the scientific method.For the findings of a study to be reproducible means that results obtained by an experiment or an observational study or in a statistical analysis of a data set should be achieved again with a high degree of reliability when the study is replicated.
By allowing some of the training data to also be included in the test set – this can happen due to "twinning" in the data set, whereby some exactly identical or nearly identical samples are present in the data set, see pseudoreplication. To some extent twinning always takes place even in perfectly independent training and validation samples.
Commonly 1–4 controls are selected for each case. Since the covariate is not measured for all participants, the nested case–control model is both less expensive than a full cohort analysis and more efficient than taking a simple random sample from the full cohort.

Bill Gates told Patrick Collison that younger generations should worry about four things. They are the climate crisis, unchecked AI, nuclear war, and the spread of disease.
Yes, some Ozempic side effects may be more common in females vs. males. However, most of the research to date has focused on the side effects of GLP-1 receptor agonists in general (the class of ...
