public double getProposalRatio(double x,
                               double y)
```
    Description copied from interface: ProposalFunction1DIfc
    
    The ratio of g(y,x)/g(x,y). The ratio of the proposal function evaluated at x = current and y = proposed, where g() is some proposal function of x and y. The implementor should ensure that the returned ratio is a valid double
    
    Specified by:
    
    getProposalRatio in interface ProposalFunction1DIfc
    
    Parameters:
    
    x - the x to evaluate
    
    y - the y to evaluate
    
    Returns:
    
    the ratio of the proposal function
  - generateProposedGivenCurrent
```
public double generateProposedGivenCurrent(double current)
```
    Specified by:
    
    generateProposedGivenCurrent in interface ProposalFunction1DIfc
    
    Parameters:
    
    current - the current state value of the chain (i.e. x)
    
    Returns:
    
    the generated possible state (i.e. y) which may or may not be accepted
