[2] Example of direct replication and conceptual replication. There are two main types of replication in statistics. First, there is a type called “exact replication” (also called "direct replication"), which involves repeating the study as closely as possible to the original to see whether the original results can be precisely reproduced. [3]
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.
An investigation of replication rates in psychology in 2012 indicated higher success rates of replication in replication studies when there was author overlap with the original authors of a study [226] (91.7% successful replication rates in studies with author overlap compared to 64.6% successful replication rates without author overlap).
Replication (scientific method), one of the main principles of the scientific method, a.k.a. reproducibility Replication (statistics), the repetition of a test or complete experiment; Replication crisis; Self-replication, the process in which an entity (a cell, virus, program, etc.) makes a copy of itself
Experiments are deemed valuable because they promote cumulative learning - the replication and extension of experimental designs are the most reliable route to it. [12] They provide learning opportunities as if a test doesn't go as planned, a researcher can use the information gained to adapt the methods used in the next experiment.
Fay's method is a generalization of BRR. Instead of simply taking half-size samples, we use the full sample every time but with unequal weighting: k for units outside the half-sample and 2 − k for units inside it. (BRR is the case k = 0.) The variance estimate is then V/(1 − k) 2, where V is the estimate given by the BRR formula above.
[3] [5] [8] As frequency of interaction between 2 or more people increases, the degree of perceived similarity and liking for one another increases eventually leading to long lasting relationships. [6] Several explanations have been offered to explain in what way similarity increases interpersonal attraction (like-prefers-like). [9]
Replication does not necessarily start at exactly the same origin sites every time, but the segments appear to replicate in the same temporal sequence regardless of exactly where within each segment replication starts. Figure 2 shows a cartoon of how this is generally envisioned to occur, while Figure 3 shows an animation of when different ...
