Collects a number of association measures for nominal and ordinal data.
Assocs(x, conf.level = 0.95, verbose = NULL)
## S3 method for class 'Assocs'
print(x, digits = 4, ...)
x |
a 2 dimensional contingency table or a matrix. |
conf.level |
confidence level of the interval. If set to |
verbose |
integer out of |
digits |
integer which determines the number of digits used in formatting the measures of association. |

further arguments to be passed to or from methods. |
This function wraps the association measures phi, contingency coefficient, Cramer's V, Goodman Kruskal's Gamma, Kendall's Tau-b, Stuart's Tau-c, Somers' Delta, Pearson and Spearman correlation, Guttman's Lambda, Theil's Uncertainty Coefficient and the mutual information.
numeric matrix, dimension [1:17, 1:3]
the first column contains the estimate, the second the lower confidence interval, the third the upper one.
