1 2	BinaryLogBiplotEM(x, freq = matrix(1, nrow(x), 1), aini = NULL, dimens = 2, nnodos = 15, tol = 1e-04, maxiter = 100, penalization = 0.2)

`x`	A binary data matrix
`freq`	A vector of frequencies.
`aini`	Initial values for the row coordinates.
`dimens`	Dimension of the solution.
`nnodos`	Number of nodes for the gaussian quadrature
`tol`	Tolerance
`maxiter`	Maximum number of iterations.
`penalization`	Penalization for the fit (ridge)
