hopsy.GaussianCoordinateHitAndRunProposal

class hopsy.GaussianCoordinateHitAndRunProposal

Mix of https://doi.org/10.1093/bioinformatics/btx052 and https://deepblue.lib.umich.edu/bitstream/handle/2027.42/3513/bal7884.0001.001.pdf. Works well when sampling a density that aligns with the coordinate directions.

Attributes

has_log_density	Returns whether the proposal knows about the log density or not.
has_negative_log_likelihood	deprecated:: 1.4 Use has_log_density instead.
log_acceptance_probability
name
proposal
proposal_log_density	Returns the log density of the proposal.

state
state_log_density	Returns the log density of the current state of the proposal.
state_negative_log_likelihood	deprecated:: 1.4 Use -state_log_density instead.
