contingencyTable: contingencyTable

In sigbertklinke/mmstat: Support for the development of interactive Shiny apps

Description

Creates a "random" contingency table of size ncol times nrow which has a total number of n observations. For n a range can be given; if a single value is given than the range round(n*0.8) till round(n*1.2) is used. With digits the number of digits after the comma for the expected frequencies can be given. With the following parameter(s) a target range of association can be given for the contingency table

CC

target range for the corrected contingency coefficient

V

target range for Cramer's V

C

target range for the contingency coefficient

chisq

target range for the chi square value

For any parameter (except chisq) given as a single value the range is computed as parameter plus/minus 0.05. If chisq) is given as a single value the range is computed as parameter plus/minus √{(ncol-1)(nrow-1)}). If more than one target parameter is given then a join of the corresponding chi square ranges will be made.

Usage

contingencyTable(tab)

Arguments

tab	a contingency table

Value

a contingency table of observed frequencies

Note

It is not guaranteed that for all parameters combinations a solution can be found. The function stops after one thousand iterations to find an appropriate table of expected or observed frequencies with an error! You may increase/enlarge the range of n, cc or increase digits.

Examples

ct <- contingencyTable(HairEyeColor[,,"Female"])
