classmethod PTMCoef.new_rw1_fromzero(knots, scale, inference=None, name='', scale_penalty=True, diagonalize_penalty=True, role='transformation_coef', noncentered=False)[source]#

Create RW1 coefficients anchored at zero.

Parameters:

  • knots (Any) – Knot vector for the spline basis.

  • scale (Var) – Scale variable used for the coefficient prior.

  • inference (Any) – Optional inference specification for the latent parameter. (default: None)

  • name (str) – Optional base name for created variables. (default: '')

  • scale_penalty (bool) – Whether to scale the penalty matrix to unit infinity norm. (default: True)

  • diagonalize_penalty (bool) – Whether to diagonalize the penalty via a eigenvalue decomposition. (default: True)

  • role (str) – Role assigned to the latent coefficient variable. (default: 'transformation_coef')

Return type:

Self

Returns:

PTMCoef – Configured coefficient with RW1 anchored at zero.
