Syntax

public double[,] GetFactorLoadings()

member GetFactorLoadings : unit -> float[,]

Type: Double
A double matrix containing the unrotated factor loadings.

Exceptions

Exception	Condition
RankException	is thrown if the rank of the covariance matrix is less than the number of factors.
NotSemiDefiniteException	is thrown if the Hessian matrix not semi-definite.
NotPositiveSemiDefiniteException	is thrown if the covariance matrix is not positive semi-definite.
SingularException	is thrown if the covariance matrix is singular.
BadVarianceException	is thrown if the input variance is not in the allowed range.
EigenvalueException	is thrown if an error occured in calculating the eigenvalues of the adjusted (inverse) covariance matrix. Check the input covariance matrix.
NonPositiveEigenvalueException	is thrown if in alpha factor analysis an eigenvalue is not positive. As all eigenvalues corresponding to the factors must be positive, either the number of factors must be reduced, or new initial estimates for the unique variances must be given.
