gof.estimates (Package: mipfp) :

This method computes three statistics to perform a test wheter the seed agrees with the target data. The statistics are the Wilk's log-likelihood ratio statistic, the Wald statistic and the Person Chi-square statistic.

Corr2Odds (Package: mipfp) : Converting correlation to odds ratio

For K binary (Bernoulli) random variables X_1, ..., X_K, this function transforms the correlation measure of association C_ij between every pair (X_i, X_j) to the odds ratio O_ij where
● Data Source: CranContrib
● Keywords: array, multivariate
● Alias: Corr2Odds

error.margins (Package: mipfp) :

This method returns the maximum deviation between each generated and desired margins of the input argument. It corresponds to the absolute maximum deviation between each target margin used to generate the estimates in the mipfp object and the generated one.
● Data Source: CranContrib
● Keywords: univar
● Alias: error.margins, error.margins.default, error.margins.mipfp

RMultBinary (Package: mipfp) : Simulating a multivariate Bernoulli distribution

This function generates a sample from a multinomial distribution of K dependent binary (Bernoulli) variables (X_1, X_2, ..., X_K) defined by an array (of 2^K cells) detailing the joint-probabilities.
● Data Source: CranContrib
● Keywords: datagen, distribution, multivariate
● Alias: Bernoulli, RMultBernoulli, RMultBinary

Array2Vector (Package: mipfp) :

Transform a N-dimensional array a to vector. The transformation is done assuming that the last index of the array moves fastest. For instance, an array a of dimensions (2,2,2) will produce the vector v = ( a[1,1,1], a[1,1,2], a[1,1,3], a[1,2,1], a[1,2,2],…,a[3,3,3] ).

GetConfInt (Package: mipfp) :

This function computes the (asymptotic) Wald confidence intervals at a given significance level for the results generated by Ipfp and ObtainModelEstimates (provided that their option compute.cov was set to TRUE).
● Data Source: CranContrib
● Keywords: multivariate
● Alias: GetConfInt

ObtainMultBinaryDist (Package: mipfp) : Generating a multivariate Bernoulli joint-distribution

This function applies the IPFP procedure to obtain a joint distribution of K multivariate binary (Bernoulli) variables X_1, ..., X_K.
● Data Source: CranContrib
● Keywords: distribution, multivariate
● Alias: ObtainMultBinaryDist

GetLinInd (Package: mipfp) :

Extracts the linearly dependant columns of matrix to obtain a matrix of full rank using QR decomposition.
● Data Source: CranContrib
● Keywords: algebra, array
● Alias: GetLinInd

flat (Package: mipfp) :

This function takes a multidimensional object and flattens it for a pretty printing. The row names are the concatenation of the original dimension names while the only column stores the initial data of the object.
● Data Source: CranContrib
● Keywords: methods, programming
● Alias: flat, flat.array, flat.default, flat.matrix, flat.table

ObtainModelEstimates (Package: mipfp) : Estimating a contingency table using model-based approaches

This function provides several alternative estimating methods to the IPFP when estimating a multiway table subject to known constrains/totals: maximum likelihood method (ML), minimum chi-squared (CHI2) and weighted least squares (WLSQ). Note that the resulting estimators are probabilities.
