plot.EKC | R Documentation |
This function generates an Empirical Kaiser Criterion (EKC) plot to visualize the eigenvalues of the actual data. The EKC method helps in determining the number of factors to retain by identifying the point where the eigenvalues exceed the reference eigenvalue. The plot provides a graphical representation to assist in factor selection.

##Take the data.bfi dataset as an example.
data(data.bfi)
response <- as.matrix(data.bfi[, 1:25]) ## loading data
response <- na.omit(response) ## Remove samples with NA/missing values
## Transform the scores of reverse-scored items to normal scoring
response[, c(1, 9, 10, 11, 12, 22, 25)] <- 6 - response[, c(1, 9, 10, 11, 12, 22, 25)] + 1
EKC.obj <- EKC(response)
## EKC plot
plot(EKC.obj)
