Two-Stage Estimation for Ultrahigh Dimensional Sparse Quadratic Discriminant Analysis
Journal of MathematicsThe conventional Quadratic Discriminant Analysis (QDA) encounters a significant hurdle due to parameter scaling complexities on the order of Op2, rendering it impractical for the analysis of high or ultrahigh dimensional data. This arises especially when

An Exponentiated Multivariate Extension for the Birnbaum-Saunders Log-Linear Model
Mathematics, 2022 In this work, a bivariate extension of the univariate exponentiated sinh-normal distribution is proposed. The properties of the new distribution, which is called the bivariate exponentiated sinh-normal distribution, are studied in detail, and the maximum
