coincid {QCA3} | R Documentation |
Produce a coincidence matrix from a crip set or fuzzy set data.
coincid(x, standardized = FALSE, use = c("complete", "pairwise")) ## S3 method for class 'coincid': print(x, digits = 3, ...)
x |
For coincide, x is a dataframe of crip set or fuzzy set data, which ranges from 0 to 1. |
standardized |
When TRUE, produce the standardized coincidence scores. |
use |
The method of handling missing data. "complete" means listwise deletion and "pairwise" means pairwise deletion. |
digits |
a non-null value for 'digits' specifies the minimum number of significant digits to be printed in values. |
... |
arguments passed to default method of print. |
Coincidence measures the amount of overlap or coincidence between two sets or configurations. The formula is:
sum(pmin(x,y))/sum(pmax(x,y))
. When standardized is TRUE, the formular is: sum(pmin(x,y))/min(sum(x),sum(y))
.
A coincidence matrix.
