rotate_factors: Rotate results

In James-Thorson/FishStatsUtils: Utilities (shared code and data) for FishStats spatio-temporal modeling toolbox

Rotate results

Description

rotate_factors rotates results from a factor model

Usage

rotate_factors(
  L_pj = NULL,
  Psi_sjt = NULL,
  Cov_pp = NULL,
  Psi_spt = NULL,
  RotationMethod = "PCA",
  testcutoff = 1e-10,
  quiet = FALSE,
  ...
)

Arguments

L_pj	Loadings matrix for 'p' categories and 'j' factors (calculated from Cov_pp if it is provided)
Psi_sjt	Array of factors (1st dimension: spatial knots; 2nd dimension: factors; 3rd dimension: time)
Cov_pp	Covariance calculated from loadings matrix. if Cov_pp is provided and L_pj=NULL, then L_pj is calculated from Cov_pp
Psi_spt	Array of projected factors (1st dimension: spatial knots; 2nd dimension: categories; 3rd dimension: time) if Psi_spt is provided and Psi_sjt=NULL, then Psi_sjt is calculated from Psi_spt and L_pj
RotationMethod	Method used for rotation when visualing factor decomposition results, Options: "PCA" (recommended) or "Varimax"
testcutoff	tolerance for numerical rounding when confirming that rotation doesn't effect results

Value

L_pj_rot
