TuckerFactors | R Documentation |
An empirical way of choosing the number of factors for FPDC. The function returns a graph and a table representing the explained variability varying the number of factors.
TuckerFactors(data = NULL, nc = 2)
data |
A matrix or data frame such that rows correspond to observations and columns correspond to variables. |
nc |
A numerical parameter giving the number of clusters |
A table containing the explained variability varying the number of factors for units (column) and for variables (row) and the corresponding plot
