Struct PrinCompOptions

Sets options for principal component analysis. The default options are also the values in PrinCompOptions.init.

Fields

Name	Type	Description
absError	double	Absolute error at which to stop the optimization procedure. Default: 1e-5
destructive	bool	Overwrite input matrix instead of copying. Ignored if the matrix passed in does not have assignable, lvalue elements and centering or scaling is enabled. Default value: false.
maxIter	uint	Maximum iterations for the optimization procedure. After this many iterations, the algorithm gives up and calls teh solution "good enough" no matter what. For exploratory analyses, "good enough" solutions can be had fast sometimes by making this value small. Default: uint.max
relError	double	Relative error at which to stop the optimization procedure. Default: 1e-4
transpose	bool	Effectively transpose the matrix. If enabled, treat each column as a data points and each row as a dimension. If disabled, do the opposite. Note that, if this is enabled, each row will be scaled and centered, not each column. Default value: false.
unitVariance	bool	Scale each column to unit variance. Note that, if this option is set to true, zeroMean is ignored and the mean of each column is set to zero even if zeroMean is false. Default value: false.
zeroMean	bool	Center each column to zero mean. Default value: true.
