Detailed Description

A container for paired-site likelihoods (likelihoods over the same sites for different models, especially topologies). An instance of this class is, roughly, a list of models, each of them having a name (stored in the modelNames attribute) and a set of site likelihoods (stored in the logLikelihoods attribute).

PairedSiteLikelihoods::PairedSiteLikelihoods	(	const std::vector< std::vector< double >> &	siteLogLikelihoods,
		const std::vector< std::string > &	modelNames = `std::vector<std::string>()`
	)

Build a new object from a site likelihoods array.

Parameters

siteLogLikelihoods	An nmodels*nsites array of loglikelihoods.
modelNames	(Optional) The names of the models.

◆ appendModel() [1/2]

void PairedSiteLikelihoods::appendModel ( const bpp::TreeLikelihoodInterface & treelikelihood )

Append a model.

Parameters

treelikelihood A TreeLikelihood record.

Exceptions

Exception If the number of sites is not the same as in the container.

◆ appendModel() [2/2]

void PairedSiteLikelihoods::appendModel	(	const std::vector< double > &	siteLogLikelihoods,
		const std::string &	modelName = `""`
	)

Append a model.

Parameters

siteLogLikelihoods	The loglikelihoods of the sites under this model.
modelName	The name of the model.

Exceptions

Exception If the number of sites is not the same as in the container.

◆ appendModels()

void PairedSiteLikelihoods::appendModels ( const PairedSiteLikelihoods & psl )

Append models by concatenation.

Parameters

psl	the PairedSiteLikelihoods object to append to the caller.

Exceptions

Exception If the number of sites in the two object is not equal.

◆ bootstrap()

std::vector< int > PairedSiteLikelihoods::bootstrap	(	std::size_t	length,
		double	scaling = `1`
	)

static

Draw a nonparametric pseudoreplicate.

Parameters

length	The length of the data.
scaling	The length of the pseudoreplicate, in fraction of the length of the data.

Returns: A vector of the same length as the data, containing the count of each element in the pseudoreplicate.

◆ computeExpectedLikelihoodWeights()

pair< vector< string >, vector< double > > PairedSiteLikelihoods::computeExpectedLikelihoodWeights ( int replicates = 10000 ) const

Compute the Expected Likelihood Weights of the models.

The weight of a model is :

$W_m = \frac{1}{B} \sum_{b \in B} \frac{L_m^{(b)}}{\sum L_k^{(b)}} = \frac{1}{B} \sum_{b \in B} \frac{exp(Y^{(b)}_m - Ymax^{(b)})}{\sum exp(Y_k^{(b)} - Y_{max}^{(b)})}$

where $Y_k^{(b)}$ is the loglikelihood of model k for replicate b.

Returns: A pair of vectors containing the names and weights of the models.

Parameters

replicates The number of pseudoreplicates over which the weights are to be averaged.
