Estimating Functions Inference to Semi‐Parametric Additive Models for Skewed And/Or Heavy‐Tailed Longitudinal Data

Australian &New Zealand Journal of Statistics, Volume 68, Issue 3, September 2026.

Early Discrimination of Maternal Haploid and Diploid Maize (Zea mays L.) Seedlings Using Morphological Traits and Random Forest Classifier

Plant Breeding, Volume 145, Issue 4, Page 822-833, August 2026.
ABSTRACT Doubled haploid (DH) technology has been widely adopted in maize (Zea mays L.) breeding programs due to its ability to reduce breeding cycle time and optimize costs. Early ploidy identification is essential for maximizing the efficiency of DH production, particularly prior to chromosome doubling.
