The K–L estimator is an estimator with a single biasing parameter, k which eliminates the biasing parameter's computational rigour as obtainable in some of the two-parameter estimators. It falls in the ridge and Liu estimator class to mitigate multicollinearity in the linear regression model. Acc...
MRReg: MDL Multiresolution Linear Regression Framework In this work, we provide the framework to analyze multiresolution partitions (e.g. country, provinces, subdistrict) where each individual data point belongs to only one partition in each layer (e.g. i belongs to subdistrict A, province P,...

Different linear combinations of L1 and L2 terms have been devised for logistic regression models, such aselastic net regularization. Random number seed: Type an integer value to use as the seed for the algorithm if you want the results to be repeatable over runs. Otherwise, a system clock v...
In R2024b: You can find the area under the ROC curve (AUC) using the auc function. rocmetrics computes pointwise confidence intervals for the performance metrics when you set the NumBootstraps value to a positive integer or when you specify cross-validated data for the true class labels (...
The function gsl_nls() solves small to moderate sized nonlinear least-squares problems with the gsl_multifit_nlinear interface with built-in support for multi-start optimization and nonlinear robust regression. For large problems, where factoring the full Jacobian matrix becomes prohibitively expensive...
We regressed the absolute PR interval on each genotype dosage using multiple linear regression with an additive genetic effect and adjusted for age, sex, height, body mass index, heart rate and any other study-specific covariates. To account for relatedness, linear mixed effects models were used ...
