    A univariate model for long-term streamflow forecasting (1991)
    Springer
    Stochastic environmental research and risk assessment 5 (1991), S. 173-188

    Notes: Abstract This paper, the first in a series of two, employs the principle of maximum entropy (POME) via maximum entropy spectral analysis (MESA) to develop a univariate model for long-term streamflow forecasting. Three cases of streamflow forecasting are investigated: forward forecasting, backward forecasting (or reconstruction) and intermittent forecasting (or filling in missing records). Application of the model is discussed in the second paper.

    Comparison of single seed descent, selective intermating and mass selection for seed size in greengram (Vigna radiata (L.) Wilczek) (1986)

    Notes: Summary Three selection methods (single seed descent (SSD), mass selection and selective intermating) were applied simultaneously to a highly heterogeneous and broadly based population of greengram. Progeny developing after two cycles of selection were evaluated for yield and seven other economic characters. The relative efficacy of each selection method was judged on the basis of the number of high yielding progeny, mean yield of top 10% progeny, and mean of the highest yielding progeny. Selection after two cycles of selective intermating was found to be the best method for generating productive progeny although mass selection favouring smaller seeds was an equally efficient method. Both of these were found superior to SSD selection.

    Comparative efficacy of pedigree selection and selective intermating in greengram (Vigna radiata (L.) Wilczek) (1985)
    Springer
    Theoretical and applied genetics 71 (1985), S. 129-132 
    Details
    ISSN: 1432-2242
    Keywords: Greengram ; Vigna radiata ; Selective intermating ; Pedigree selection
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Selective intermating and pedigree selection methods were applied simultaneously to highly heterogeneous and heterozygous base populations of greengram in order to compare their relative efficacy in terms of evolving the number of productive lines as well as their production potential. Selection after two cycles of selective intermating was found to be a better method than traditional pedigree selection. The demerits of pedigree selection and merits of selective intermating are discussed. It is suggested that selective intermating replace the widely adopted but less effective pedigree selection for generating promising new material in such autogamous crops as greengram.

    Evaluation of rainfall networks using entropy: II. Application (1992)
    Springer
    Water resources management 6 (1992), S. 295-314

    ISSN: 1573-1650
    Keywords: Entropy ; isoinformation contours ; maximum entropy ; rainfall networks ; variance reduction

    Topics: Architecture, Civil Engineering, Surveying , Geography
    Notes: Abstract This paper, the second in the series, applies the entropy approach to space and time evaluation of rainfall networks in Louisiana. The evaluation is made for five sampling intervals: daily, 2-day, weekly, monthly, and yearly, and for two separate seasons. In each case, the best combination of raingages is suggested and the lines of equal information (isoinformation contours) are constructed showing the areas of greater or less information transfer. The isoinformation lines are especially suitable in decisions concerning the expansion of the existing network or deleting the unnecessary raingages.

    Notes: Abstract This paper, the first in a series of two, develops an entropy-based approach for evaluating rainfall networks. Space and time dependencies between raingages are examined by autocovariance and cross-covariance matrices. Multivariate distributions, associated with different dependencies, are obtained using the principle of maximum entropy (POME). Formulas for entropy (uncertainty in data of one raingage), joint entropy (uncertainty in data of two or more raingages) and transinformation (common information content among two or more raingages) are derived for each distribution, based on normal data. The decision whether to keep or eliminate a raingage depends entirely on reduction or gain of information at that raingage. The lines of equal information (isoinformation contours) are defined by considering two raingages (bivariate case) and many raingages (multivariate case).

    Parameter estimations for 2-parameter Pareto distribution by pome (1995)
    Springer
    Water resources management 9 (1995), S. 81-93

    ISSN: 1573-1650
    Keywords: Entropy ; moments ; maximum likelihood ; Pareto distribution ; POME

    Notes: Abstract The principle of maximum entropy (POME) was employed to derive a new method of parameter estimation for the 2-parameter Pareto distribution. Monte Carlo simulated data were used to evaluate this method and compare it with the methods of moments (MOM), probability weighted moments (PWM), and maximum likelihood estimation (MLE). The parameter estimates yielded by POME were either superior or comparable for small sample sizes when bias and RMSE were used as the criteria, and were either comparable or adequate for large sample sizes.
