    Area of Science:

    • Statistics
    • Biometry
    • Computational Biology

    Background:

    • Estimating dendritic tree branching parameters is challenging due to incomplete data from cut branches.
    • This problem involves estimating bivariate discrete distributions with partially censored observations, akin to multinomial classification with supplemental data.

    Purpose of the Study:

    • To develop statistical methods for estimating branching and cutting parameters in dendritic trees with censored data.
    • To derive tests for random censoring and estimators for parameters under random censoring.

    Main Methods:

    • Developed tests for the randomness of censoring.
    • Derived estimators for parameters assuming random censoring.
    • Applied these methods to analyze dendritic tree data.
