Description
fa.init estimates initial parameter values for factor analytic models from the observed variance-covariance matrix.
Usage
fa.init(data, model, scale = 1)
Arguments
data |
A data frame containing the response and the base factors in the factor analytic (compound) model term. |
model |
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 “sfa“, “facv“, “fa” or rr with an optional argument k specifying the order of the factor analytic model. Other model functions are not allowed. |
scale |
Scales the variance-covariance matrix prior to calculating the parameter estimates (default is 1.0). |
Value
A numeric vector of specific variances followed by the loadings if the factor analytic function is fa or rr, otherwise a numeric vector of loadings followed by the specific variances.
Examples
## Not run: init <- fa.init(data, fa(site,2):variety) ## End(Not run)
