    • Generalized AMMI Models for Assessing The Endurance of Soybean to Leaf Pest 

      HADI, Alfian F.; MATTJIK, AA; SUMERTAJAYA, IM (Jurnal ILMU DASAR, 2010-07-05)
      AMMI (Additive Main Effect Multiplicative Interaction) model for interactions in two-way table provide the major mean for studying stability and adaptability through genotype × environment interaction (GEI), which modeled ...

      HADI, Alfian F.; MATTJIK, AA; SUMERTAJAYA, IM (International Journal of Scientific & Technology Research, 2020-12-16)
      AMMI (Additive Main Effect Multiplicative Interaction) model for interactions in two-way table provide the major mean for studying stability and adaptability through genotype × environment interaction (GEI), which modeled ...

    • Penduga Maksimum Likelihood untuk Parameter Dispersi Model Poisson-Gamma dalam Konteks Pendugaan Area Kecil 

      HADI, Alfian F.; NUSYIRWAN; NOTODIPUTRO, Khairil Anwar (FMIPA Universitas Negeri Yogyakarta, 2008-11-30)
      The Poisson-Gamma (Negative Binomial) distribution is considered to be able to handle overdispersion better than other distributions. Estimation of the dispersion parameter, φ, is thus important in refining the predicted ...

    • Profile Analysis in Clustering with Hotelling’s T-Square Statistics 

      SAPUTRO, Dewi R. S.; HADI, Alfian F.; WIBAWA, Gusti N. A. (International Conference Of Mathematics and Mathematics Education (I-Cmme) 2021, 2022-11-28)
      Cluster analysis is a multivariate technique that groups objects based on their characteristics. For instance, it groups the most closely similar objects in the same cluster, thereby forming high internal homogeneity and ...

    • Row-Column Interaction Models for Zero-Inflated Poisson Count Data in Agricultural Trial 

      HADI, Alfian F.; SA’DIYAH, Halimatus (ICCS-13, 2023-03-14)
      Many zero observations makes some difficulties and fatal consequence in Poisson modeling and its interpretation. We consider to facilitates the analysis of two-way tables of count with many zero observations in ...

    • Row–column interaction models, with an R implementation 

      YEE, Thomas W.; HADI, Alfian F. (Computational Statistics, 2014-03-27)
      We propose a family of models called row–column interaction models (RCIMs) for two-way table responses. RCIMs apply some link function to a para meter (such as the cell mean) to equal a row effect plus a column effect ...
