This is the third post with LaplacesDemon tuning. same problem, different algorithms. For introduction and other code see this post. The current post takes algorithms Independence Metropolis to Reflective Slice Sampler.

Independence Metropolis

Independence Metropolis expects first a run of e.g. LaplaceApproximation and to be fed the results of that. It should be noted that LaplaceApproximation() did not think it has converged, but I continued anyway.
LA <- LaplaceApproximation(Model,
    parm=Initial.Values,
    Data=MyData)
LA$Summary1[,1]# mode
LA$Covar       # covariance
Fit <- LaplacesDemon(Model,
    Data=MyData,
    Covar=LA$Covar,
    Algorithm=’IM’,
    Specs=list(mu=LA$Summary1[,1]),
    Initial.Values = Initial.Values
)
Call:
LaplacesDemon(Model = Model, Data = MyData, Initial.Values = Initial.Values,
    Covar = LA$Covar, Algorithm = “IM”, Specs = list(mu = LA$Summary1[,
        1]))

Interchain Adaptation

This works on cluster computers only, hence is skipped.

Metropolis-Adjusted Langevin Algorithm

It has specs, the defaults are used. Somehow it ends up proposing thinning 1000 so that is taken.

Metropolis-Coupled Markov Chain Monte Carlo

This algorithm is suitable for multi-modal distributions. Thus not for this specific problem. It also requires at least two cores, which brings it just within my current computing capability. The two cores are used for keeping two chain between which some swapping is done. From examination of my processor occupancy it did not tax either core to the max. As a consequence the algorithm does not run very fast. From what I read the approach is that one makes a first run, takes the covariance of this run as base for the second run and so on. The first run can be started with a small diagonal covariance matrix. There was still quite some change from run one to two, so I did a third run as final. I did not take a fourth run to do the recommended thinning.

Multiple-Try Metropolis

The first run took half an hour. During the run I could see LP of way from the target distribution. On a whim,  I did a second run, with a covariance matrix from LaplaceApproximation() as added information. This run was better but took another half hour.

Oblique Hyperrectangle Slice Sampler

I tried to get close or over to the number of discarded samples for the stationary run. As before, that point varied. I did not feel like running a thinning of 390, so stopped here. Just to be precise, spec variable A refers to the number of thinned samples, which translates, in this case to 12000 un-thinned samples.

Random-Walk Metropolis

This algorithm required tuning of the covariance matrix, which can be done from previous runs. Hence I started with diagonal and did three subsequent runs. The second run had no stationary samples, so I took all. I did not think setting Thinning to 20 worth the effort of making a fourth run for this exercise (but would have if the result were important, rather than training myself on these algorithms).

Fit1 <- LaplacesDemon(Model,
    Data=MyData,
    Algorithm=’RWM’,
    Covar=diag(.001,nrow=2),
    Initial.Values = Initial.Values
)
Fit2 <- LaplacesDemon(Model,
    Data=MyData,
    Algorithm=’RWM’,
    Covar=var(Fit1$Posterior2),
    Initial.Values = apply(Fit1$Posterior2,2,median)
)
Fit3 <- LaplacesDemon(Model,
    Data=MyData,
    Algorithm=’RWM’,
    Covar=var(Fit2$Posterior1),
    Initial.Values = apply(Fit2$Posterior1,2,median)
)

Call:
LaplacesDemon(Model = Model, Data = MyData, Initial.Values = apply(Fit2$Posterior1,
    2, median), Covar = var(Fit2$Posterior1), Algorithm = “RWM”)

Reflective Slice Sampler

The manual describes this as a difficult algorithm to tune. Indeed it seems that my runs did not give the desired result.
