fa.init estimates initial parameter values for factor analytic models from the observed variance-covariance matrix.
fa.init(data, model, scale = 1)
||A data frame containing the response and the base factors in the factor analytic (compound) model term.|
||A two sided formula with the response on the left and a first order interaction with a factor analytic model term on the right. Valid factor analytic model functions are “
||Scales the variance-covariance matrix prior to calculating the parameter estimates (default is 1.0).|
A numeric vector of specific variances followed by the loadings if the factor analytic function is
rr, otherwise a numeric vector of loadings followed by the specific variances.
