A table contingency is a matrix table that shows the variables’ frequency distribution in means of joint frequencies statistics and marginal frequencies in statistics. Creating Contingency Table The table below, for example, shows events related to computer sales at a fictional store.

Oct 4, 2018 · I have 2 categorical variables for each observation in my dataset: environment and behaviour. I'm trying to test association between them i.e. does the environment affect behaviour? The resulting contingency table is: Behv1 Behv2 Behv3 Behv4 Env 1 …

Nov 1, 2016 · This approach wouldn't use a contingency table, so it may not be the sort of answer you're looking for, but for a research question such as you describe, "Is the effect of smoking on cancer occurrence different for males and females?", logistic regression would be one way of finding an answer.

Apr 23, 2015 · A correspondence analysis is analogous to running a principal components analysis on both the rows and the columns of the contingency table. Then both are plotted together with a biplot. Here is an R based example using the data from @xan's answer:

A pivot table is one of the possible ways of creating a contingency table. A typical pivot table has the visual form of the contingency table, although a pivot table might have only one column or even zero etc. The pivot operation in spreadsheet software can be used to generate a contingency table from sampling data. However you may use the ...

If you're looking for other ways to compute Fisher's exact test with larger contingency tables, here is a online calculator for Fisher's exact test for 2x3 contingency tables. Also, here's one for 3x3 contingency tables, and one for 2x4 contingency tables.

Nov 9, 2020 · $\begingroup$ Hello, it's true in this particular contingency table the Fisher and Chi square is NS, so I don't need to compare any two groups. However, one of my contingency tables is 0/26, 2/36 and 4/8 (yes/no) and this gives me a significant result. To then determine which two groups differ significantly, would I do 2x2 Fisher tests? $\endgroup$

Sep 19, 2017 · I want to generate this table using bootstrap resampling.from the given data. I need to check whether some inequalities involving the cell counts are satisfied for each sample. For that, I need to generate the table first. I know how to do bootstrapping in a $2\times 2$ table using uniform random numbers.

Dec 4, 2014 · In this case there are 5 true positives, 2 false positives, 3 false negatives, and 8 true negatives. You can ultimately use this table to derive many other statistics (e.g. Accuracy, Kappa, Sensitivity, etc). The generic contingency table is simply a representation of the distribution of groups in a population. For example (copying from wikipedia):

(It is discrete because, with only a finite number of instances represented in a contingency table, there are a finite number of possible realized values that this statistic can take on.) Notwithstanding this fact, it is compared to a continuous reference distribution (viz., the $\chi^2$ distribution with degrees of freedom $(r-1)(c-1)$). This ...
