% -------------------------------------------------------------------------
% DEscriptION:
% This function computes the final model logistic regression coefficients
% using bootstrap resampling and it associated multivariable model
% response and bootstrap confidence intervals. See ref. [1] for more
% details. This function uses logistic regression utilities from DREES
% as well as a rounding function written by
% Francois Beauducel available at:

% MRI texture features for the prediction of lung metastases in soft-tissue

% INPUTS:
% - X: Matrix of size [nInst X nFeat] specifying the numerical data of the
% features of the input features where ‘nInst‘ refers to the number
% of instances in X and ‘nFeat‘ to the number of features in X.
% Each column is a different feature.
% - Y: Column vector of size [nInst X 1] specifying the outcome status
% (1 or 0) for all instances.
% - imbalance: String specifying the type of imbalance-adjustement strategy
% employed. Either ‘IABR‘ for imbalance-adjusted bootstrap
% resampling (see ref.[1]) or ‘IALR‘ for imbalance-adjusted
% logistic regression (see ref.[2]).
% - batchNum: (optional input). If present integer that specifies the
% batch number for parallelization purposes.
% -------------------------------------------------------------------------
% OUTPUTS:
% - coeff: Column vector of size [nCoeff+1 X 1] specifying the final
% logistic regression coefficients. Last entry specify the offset
% of the model.
% - resp: Column vector of size [nInst X 1] specifying the linear
% multivariable model response when ‘coeff‘ is applied to ‘X‘.
% - modelCI: Column vector of size [nInst X 2] specifying the 95%
% confidence interval on the multivariable model response as
% defined by the 2.5 (modelCI(i1)) and the 97.5 (modelCI(i2))
% percentiles for the ith instance. See ref. [1] for more
% details.
% - coeff_boot: Array of size [nCoeff X 1000] where 1000 is the number of
% bootstrap samples used to calculate the mean coefficients
% (‘coeff‘ output #1). Each column
