Detailed Description

Likelihood-ratio test for binomial data.

This class is useful when having binomial data for several populations and especially comparing the frequency in the differen samples.

Constructor & Destructor Documentation

◆ LikelihoodRatioTestBinomial()

theplu::yat::statistics::LikelihoodRatioTestBinomial::LikelihoodRatioTestBinomial ( size_t n = 2 )

constructor

Parameters

n	number of populations in data

Member Function Documentation

◆ add()

void theplu::yat::statistics::LikelihoodRatioTestBinomial::add	(	size_t	population,
		bool	positive,
		long int	n = `1`
	)

add one data point

Parameters

population	from which population the data point comes from.
positive	if `true` data point is positive.
n	how many data points added

◆ llr()

double theplu::yat::statistics::LikelihoodRatioTestBinomial::llr ( void ) const

Calculate natural logarithm of likelihood ratios.

The logairithm of the likelihood ratio is calculated as $LLR = \sum_i \left ( n_{i+} \ln \frac{n_{i+}}{n_i} + n_{i-} \ln \frac{n_{i-}}{n_i} \right ) - \left ( n_+ \ln \frac{n_+}{n} + n_- \ln \frac{n_-}{n} \right )$

◆ n() [1/2]

unsigned long int theplu::yat::statistics::LikelihoodRatioTestBinomial::n ( void ) const

Returns: Number of data points

◆ n() [2/2]

unsigned long int theplu::yat::statistics::LikelihoodRatioTestBinomial::n ( size_t i ) const

Returns: Number of data points from population i

◆ negative() [1/2]

unsigned long int theplu::yat::statistics::LikelihoodRatioTestBinomial::negative ( void ) const

Returns: Number of negative data points

◆ negative() [2/2]

unsigned long int theplu::yat::statistics::LikelihoodRatioTestBinomial::negative ( size_t i ) const

Returns: Number of negative data points from population i

◆ positive() [1/2]

unsigned long int theplu::yat::statistics::LikelihoodRatioTestBinomial::positive ( void ) const

Returns: Number of data points

◆ positive() [2/2]

unsigned long int theplu::yat::statistics::LikelihoodRatioTestBinomial::positive ( size_t i ) const

Returns: Number of positive data points from population i

◆ size()

size_t theplu::yat::statistics::LikelihoodRatioTestBinomial::size ( void ) const

Returns: Number of populations
