    Index
    control? covmat? nObs? rotation? scores?
    control?: { lower?: number; start?: readonly number[] }

    Settings of the optimisation (part of R's control list).

    Type Declaration

    • Optionallower?: number

      Lower bound of the uniquenesses. Default 0.005.

    • Optionalstart?: readonly number[]

      Starting uniquenesses. Default (1 - factors / (2p)) / diag(solve(S)).

    covmat?: readonly (readonly number[])[]

    A covariance (or correlation) matrix to analyse instead of the data x (pass null as x).

    nObs?: number

    The number of observations behind covmat (for the test statistic). Default: unknown.

    rotation?: FactanalRotation

    Default "varimax".

    scores?: FactanalScores

    Factor scores to compute from the data (R's scores): "none" (default), "regression" (Thomson's, z R^-1 L) or "Bartlett" (z W L (L' W L)^-1 with W = diag(1 / uniquenesses)), where z is the data standardised by column (denominator n - 1), R its correlation matrix and L the final loadings. Scores need x: with covmat they are an error.
