FactorRotations.jl

FactorRotations v0.5.0

Diff since v0.4.0

Breaking changes

• Enzyme.jl dependency moved to a package extension to improve package load times. If automatic differentiation is required for ComponentLoss or a custom rotation method it is now required to explicitly load Enzyme.jl via using Enzyme.

Merged pull requests:

• Move Enzyme.jl into extension (#71) (@alyst)

FactorRotations v0.4.0

Diff since v0.3.1

Breaking changes

• Diverging rotations now print a warning instead of throwing a ConvergenceError

Merged pull requests:

• parallelize rotation with random starts (#70) (@p-gw)

• Implement Parsimax (#28)
• Varimax did not converge for echelon-pattern matrix (#48)

FactorRotations v0.3.0

Diff since v0.2.4

Breaking changes

• Custom rotation criteria must now implement in-place criterion_and_gradient! instead of criterion_and_gradient
• The epsilon parameter in Absolmin must now be striclty positive since epsilon = 0 leads to nonfinite gradients
• rotate now reflects the columns of the rotated loading matrix by default
• atol function argument for rotate is now called g_atol

New Features

• Columns of rotated loading matrices can now be reflected by calling reflect, reflect!, or using the reflect function argument for rotate (default: true)
• rotate gains a new function argument normalize (default: false) that performs Kaiser normalization before rotation and denormalizes the rotated loading matrix after rotation
• rotate gains a new function argument f_atol that sets the absolute tolerance for the comparison of minimum values with random starts
• Logging for rotate is improved: You can now set logperiod to control how often the optimization state is logged
