FactorAnalysis.VarianceEstimationMethod Property

The variance estimation method.

public int VarianceEstimationMethod {get; set;}

Property Value

An int used to designate the method to be applied for obtaining the initial estimates of the unique variances.

Remarks

By default, VarianceEstimationMethod is set to 1.

init Method
0 Initial estimates are taken as the constant 1-nfactors/(2*nvar) divided by the diagonal elements of the inverse of input matrix cov.
1 Initial estimates are input by the user in vector uniq.

Note that when the factor loading estimation method is PrincipalComponent, the initial estimates in uniq are reset to 0.0.
