faPlot: Plot the resulted FA hyperplane

In aciobanusebi/s2fa: Factor Analysis (FA), Simple Supervised FA (S2FA), Simple Semi-Supervised FA (S3FA), Missing S3FA (MS3FA)

Description

Works only if input is 1- or 2-dimensional and output is 1-dimensional.

Usage

faPlot(X_t, Z_t, p, color = "red", add = FALSE, addPoints = FALSE,
  pointsColor = "black", addLr = FALSE, lrColor = "blue",
  checkArgs = TRUE, checkPositiveDefinite = FALSE)

Arguments

X_t	a matrix representing the input points to be plotted (if addPoints is TRUE); usually, the training input
Z_t	a matrix representing the output = values of function in input points; usually, the training output
p	parameters of a fitted FA
color	color of the hyperplane given by FA
add	add this plot to an already existing plot?
addPoints	whether to plot the points X_t, Z_t
pointsColor	color of points
addLr	fit and add a linear regression model on plot?
lrColor	color of linear regression hyperplane
checkArgs	whether to check the arguments are valid; it takes more time to execute
checkPositiveDefinite	whether to check the covariance matrices are valid; it takes more time to execute

Examples

params <- faFit(X_t_unsupervised = house[,2:3,drop=FALSE],
                paramsNULL_nDimZ = 1,
                params=NULL,
                type="fa",
                lambdaRidge=0,
                checkArgs=FALSE,
                checkPositiveDefinite=FALSE,
                epsilon=1e-10,
                maxIterations=100,
                stopType="parameter",
                turboEmMethods=c("em","pem"))
