This symbol represents a proposal distribution.
This symbol represents a proposal distribution, used to generate proposals \( \htmlClass{sdt-0000000081}{\mathbf{x}^*} \) for the sampling sequence.
The symbol \( P_{\text{prop}} \) represents the proposal distribution which is used to generate proposals for the sampling sequence. Given the previous state \( \htmlClass{sdt-0000000046}{\mathbf{x}}_n \), this distribution is used to get possible new states \( \htmlClass{sdt-0000000081}{\mathbf{x}^*} \) used as options for the next sampled value \( \htmlClass{sdt-0000000046}{\mathbf{x}}_{n+1} \).
