    Rice is the third most important crop in Kenya after maize and wheat. Plant parasitic nematodes (PPN) are a major rice production constraint. The objective of this study was to determine the distribution and abundance ...
  • Cole, Donald C.; Levin, Carol; Loechl, Cornelia; Thiele, Graham; Grant, Frederick; Girard, Aimee W.; Sindi, Kirimi; Low, Jan (Elsevier, 2016-03)
    Multi-sectoral programs that involve stakeholders in agriculture, nutrition and health care are essential for responding to nutrition problems such as vitamin A deficiency among pregnant and lactating women and their infants ...
  • Shahar, Doron J. (Scientific Research Publishing, 2017-04)
    It is common practice in science to take a weighted average of estimators of a single parameter. If the original estimators are unbiased, any weighted average will be an unbiased estimator as well. The best estimator among ...
  • Paris, Quirino; Caracciolo, Francesco (Scientific Research Publishing, 2017-04)
    A test of the adding up condition in demand systems is crucial for determining whether a share format is admissible when the number of sample goods is smaller than the number of commodity choices available to consumers. ...
  • Pyeye, Sarah; Syengo, Charles K.; Odongo, Leo; Orwa, George O.; Odhiambo, Romanus O. (Scientific Research Publishing, 2016-12)
    The study focuses on the imputation for the longitudinal survey data which often has nonignorable nonrespondents. Local linear regression is used to impute the missing values and then the estimation of the time-dependent ...
  • Ogoke, Petronilla U.; Nduka, Chinaka E.; Soyinka, Ajibola T. (Scientific Research Publishing, 2016-12)
    Owing to the fact that the major challenge of predicting the risk of having bipolar is the absence of a gold standard to distinguish between true cases and false positive; this study employed the extension of cubic spline ...
  • Liu, Haoge; Guan, Jianhe (Scientific Research Publishing, 2016-10)
    Nowadays fuzzy concepts are frequently used as statistical parameters, while the traditional normal distribution can only accept determinate variable. In order to design a practical model for fuzzy statistic events, this ...
  • Chiba, Yasutaka (Scientific Research Publishing, 2016-10)
    The main purpose in many randomized trials is to make an inference about the average causal effect of a treatment. Therefore, on a binary outcome, the null hypothesis for the hypothesis test should be that the causal risks ...
  • Juajibioy, Juan C. (Scientific Research Publishing, 2016-10)
    In this paper, we introduce the survival modelling methodology in order to identify some factors which may be influencing the university dropout. By using the data base provided by the Fundación Universidad Autónoma de ...
  • Kung’u, John; Nderitu, Joseph (Scientific Research Publishing, 2016-08)
    In this paper, we have proposed estimators of finite population mean using generalized Ratio- cum-product estimator for two-Phase sampling using multi-auxiliary variables under full, partial and no information cases and ...
  • Shanubhogue, Ashok; Sinojiya, Ankit R. (Scientific Research Publishing, 2017-02)
    We have proposed a new generalized Weibull-exponential frailty model which is a general case of classical frailty model suggested by [1] and [2]. In classical frailty model, modeling of hazard rate is considered whereas, ...
  • Akinwande, Michael O.; Dikko, Hussaini G.; Samson, Agboola (Scientific Research Publishing, 2015-12)
    Suppression effect in multiple regression analysis may be more common in research than what is currently recognized. We have reviewed several literatures of interest which treats the concept and types of suppressor variables. ...
  • Uzoma, Umeh E.; Jeremiah, Obulezi O. (Scientific Research Publishing, 2016-02)
    Outlier detection is an important data screening type. RIM is a mechanism of outlier detection that identifies the contribution of data points in a regression model. A BIC-based RIM is essentially a technique developed in ...
  • Cassidy, Daniel T. (Scientific Research Publishing, 2016-02)
    Some moments and limiting properties of independent Student’s t increments are studied. Inde-pendent Student’s t increments are independent draws from not-truncated, truncated, and effectively truncated Student’s t-distributions ...
  • Morana, Claudio (Scientific Research Publishing, 2015-12)
    The paper introduces a new Frequentist model averaging estimation procedure, based on a stacked OLS estimator across models, implementable on cross-sectional, panel, as well as time series data. The proposed estimator shows ...
  • Greenacre, Zerrin A. (Scientific Research Publishing, 2016-06)
    Nowadays, internet-based surveys are increasingly used for data collection, because their usage is simple and cheap. Also they give fast access to a large group of respondents. There are many factors affecting internet ...
  • Jere, Stanley; Siyanga, Mubita (Scientific Research Publishing, 2016-04)
    In this paper, the Holt’s exponential smoothing and Auto-Regressive Integrated Moving Average (ARIMA) models were used to forecast inflation rate of Zambia using the monthly consumer price index (CPI) data from May 2010 ...
  • Umeh, Edith U.; Eriobu, Nkiru O. (Scientific Research Publishing, 2016-04)
    This paper, comparison of two sample tests, is motivated by the fact that in the test of significant difference between two independent samples, numerous methods can be adopted; each may lead to significant different ...
  • Eze, F. C.; Nwankwo, E. U. (Scientific Research Publishing, 2016-04)
    The expected mean squares for unbalanced mixed effect interactive model were derived using Brute Force Method. From the expected mean squares, there are no obvious denominators for testing for the main effects when the ...
  • Jere, Stanley; Moyo, Edwin (Scientific Research Publishing, 2016-04)
    In this paper, the Box-Jenkins modelling procedure is used to determine an ARIMA model and go further to forecasting. We consider data of Malaria cases from Ministry of Health (Kabwe District)-Zambia for the period, 2009 ...
