The amount of time needed to cook a chicken depends on the temperature and cooking method used. For example, roasting a 7-pound chicken in the oven at 350 degrees Fahrenheit typically takes between 20 and 30 minutes per pound, or up to 2.5 ...Pairwise comparison example. The pairwise comparison can be used very well to weight the criteria for a benefit analysis. For our example we suppose an assembly is to be designed and there are several designs from which a design must be selected for further elaboration. In order to be able to make this decision, a benefit analysis is prepared.

For example, a Tukey test (Tukey, 1977) can accommodate all pairwise comparisons of means, whereas the Dunnett test (Dunnett, 1955) allows for only a comparison between a single control group mean and each of the treatment group means. Thus, the Tukey test would have a more stringent alpha level than the Dunnett test to accommodate the extra ...The best-worst method (BWM) is a multicriteria decision-making (MCDM) method to derive the relative importance (weight) of a set of criteria used to evaluate a set of alternatives. Several models (e.g., nonlinear, linear, Bayesian, and multiplicative) have been developed to find the weights based on the provided pairwise comparisons, conducted ...Here's how it works. Take the observed (uncorrected) p-value and multiply it by the number of comparisons made. What does this mean in the context of the previous example, in which alpha was set at .05 and there were three pairwise comparisons? It's very simple. Suppose the LSD p-value for a pairwise comparison is .016. This is an unadjusted p ...We visually compared the width of the confidence intervals from the different statistical methods. For each dataset and pairwise comparison, a ratio of the confidence interval widths from the two methods was calculated and then scaled so that the comparison method confidence interval spanned -0.5 to 0.5. p-valuesFunction notation is a method of writing algebraic variables as functions of other variables. Most often, functions are portrayed as a set of x/y coordinates, with the vertical y-axis serving as a function of x. For example, writing “f(x) =...

The simplest such fall-back methods involve entirely disregarding the results of the pairwise comparisons. For example, the Black method chooses the Condorcet winner if it exists, but uses the Borda count instead if there is a cycle (the method is named for Duncan Black).

Even though the above example could not determine if the method of pairwise comparisons satisfies or violates the Condorcet criterion, you might be able to make an educated guess based on this example. Determine whether pairwise comparisons satisfies or violates the Condorcet criterion, and explain why.

A Condorcet method (English: / k ɒ n d ɔːr ˈ s eɪ /; French: [kɔ̃dɔʁsɛ]) is an election method that elects the candidate who wins a majority of the vote in every head-to-head election against each of the other candidates, that is, a candidate preferred by more voters than any others ...Alpha is your significance level for a single comparison, and C equals the number of comparisons. The experiment-wise error rate represents the probability of a ...MULTIPLE COMPARISONS METHOD 4 Since there are multiple pairwise comparisons, exactly ( −1)/2 comparisons, a multiplicity adjustment is required. For example, if a target overall or family-wise significance level, 𝛼, is given, then one common approach, known as the Bonferroni correction, is to choose the

Sequence alignment. In bioinformatics, a sequence alignment is a way of arranging the sequences of DNA, RNA, or protein to identify regions of similarity that may be a consequence of functional, structural, or evolutionary relationships between the sequences. [1] [2] Aligned sequences of nucleotide or amino acid residues are typically ...The simplest such fall-back methods involve entirely disregarding the results of the pairwise comparisons. For example, the Black method chooses the Condorcet winner if it exists, but uses the Borda count instead if there is a cycle (the method is named for Duncan Black). To complete this analysis we use a method called multiple comparisons. Multiple comparisons conducts an analysis of all possible pairwise means. For example, with three brands of cigarettes, A, B, and C, if the ANOVA test was significant, then multiple comparison methods would compare the three possible pairwise comparisons: Brand A to Brand B ...Pairwise comparison of vectors with unequal sizes and unequal variances. I have 3 vectors which are unequal in size (lengths: 21, 33 and 7). Each vector contains ratio of bug-to-duplicate bugs in 3 different time periods.
