2. Pseudoreplication - Wikipedia

   en.wikipedia.org/wiki/Pseudoreplication

   Inferential statistics cannot separate variability due to treatment from variability due to experimental units when there is only one measurement per unit. Sacrificial pseudoreplication (Figure 5b in Hurlbert 1984) occurs when means within a treatment are used in an analysis, and these means are tested over the within unit variance.

3. Replication (statistics) - Wikipedia

   en.wikipedia.org/wiki/Replication_(statistics)

   Replication in statistics evaluates the consistency of experiment results across different trials to ensure external validity, while repetition measures precision and internal consistency within the same or similar experiments. [5] Replicates Example: Testing a new drug's effect on blood pressure in separate groups on different days.

4. Spreadsheet - Wikipedia

   en.wikipedia.org/wiki/Spreadsheet

   Formulas in the B column multiply values from the A column using relative references, and the formula in B4 uses the SUM() function to find the sum of values in the B1:B3 range. A formula identifies the calculation needed to place the result in the cell it is contained within. A cell containing a formula, therefore, has two display components ...

5. PRESS statistic - Wikipedia

   en.wikipedia.org/wiki/PRESS_statistic

   Given this procedure, the PRESS statistic can be calculated for a number of candidate model structures for the same dataset, with the lowest values of PRESS indicating the best structures.

6. Accounting equation - Wikipedia

   en.wikipedia.org/wiki/Accounting_equation

   A company's quarterly and annual reports are basically derived directly from the accounting equations used in bookkeeping practices. These equations, entered in a business's general ledger , will provide the material that eventually makes up the foundation of a business's financial statements .

7. Compositional data - Wikipedia

   en.wikipedia.org/wiki/Compositional_data

   In probability and statistics, a partition of the sampling space into disjoint events is described by the probabilities assigned to such events. The vector of D probabilities can be considered as a composition of D parts. As they add to one, one probability can be suppressed and the composition is completely determined.

8. Kernel (statistics) - Wikipedia

   en.wikipedia.org/wiki/Kernel_(statistics)

   In statistics, especially in Bayesian statistics, the kernel of a probability density function (pdf) or probability mass function (pmf) is the form of the pdf or pmf in which any factors that are not functions of any of the variables in the domain are omitted. [1] Note that such factors may well be functions of the parameters of the

9. Generalized estimating equation - Wikipedia

   en.wikipedia.org/wiki/Generalized_estimating...

   In statistics, a generalized estimating equation (GEE) is used to estimate the parameters of a generalized linear model with a possible unmeasured correlation between observations from different timepoints. [1] [2]
