pymc.distributions.transforms.SumTo1

class pymc.distributions.transforms.SumTo1(ndim_supp=None)

Transforms K - 1 dimensional simplex space (k values in [0,1] and that sum to 1) to a K - 1 vector of values in [0,1] This Transformation operates on the last dimension of the input tensor.

Methods

SumTo1.__init__([ndim_supp])
SumTo1.backward(value, *inputs)	Invert the transformation.
SumTo1.forward(value, *inputs)	Apply the transformation.
SumTo1.log_jac_det(value, *inputs)	Construct the log of the absolute value of the Jacobian determinant.
