On Local Linear Regression Estimation of Finite Population Totals in Model Based Surveys
(University of Nairobi, 2018)In this paper, nonparametric regression is employed which provides an estimation of unknown finite population totals. A robust estimator of finite population totals in model based inference is constructed using the procedure ... -
On maintainable grade structures in an educational system
(University of Nairobi.School of Mathematics, 1999) -
On Modelling and Pricing Rainfall Derivatives with Seasonality
(2011)We are interested in pricing rainfall options written on precipitation at specific locations. We assume the existence of a tradeable financial instrument in the market whose price process is affected by the quantity of ... -
On multi-type step-wise group screening designs
(The Allahabad mathematical society, 2002) -
On multistage group screening designs
(Department of mathematics, 2010)In this article we discuss multistage group screening in which group-factors contain differing number of factors. We describe a procedure for grouping the factors in the absence of concrete prior information, so that the ... -
On quasi-similarity and putnam-fuglede property of operators in Hilbert spaces
(University of Nairobi, 2014)The problem of finding conditions under which two given operators say A and B have equal spectra has been considered by several authors. In this paper we show that quasi-similar operators 𝐴 and 𝐵 which satisfy the Putnam- ... -
On reflectionless equi-transmitting matrices
(2014)Reflectionless equi-transmit.ting unitary matrices are studied in connection to matching conditions in quantum graphs. All possible such matrices of size G are described explicitly. It is shown that such matrices form 30 ... -
ON SMOOTHING TIME SERIES DATA USING A CLASSICAL MOVING AVERAGE FORMULA
(Department of Mathematics, University of Nairobi, 2002)In time series realizations, assuming that the trend component to be approximated by a polynomial in time, smoothing filters based on a moving-average formula are proposed which link the degree of this polynomial to the ... -
On sociology and behaviour in impala (aepyceros (melampus lichtenstein)
(University of Nairobi, 1966-08)1. The required habitat of impala, association with other herbivores and the relation to predators are outlined. 2. The commonest types of group formation - female herd with dominant male and bachelor herd - and the ... -
On spectral properties of -commuting operators in Hilbert spaces
(School of Mathematics, University of Nairobi, 2012)Let B(H) denote the Banach algebra of bounded linear operators on a complex Hilbert space H and let A;B 2 B(H) satisfying the equation; AB = BA; 2 C;AB 6= 0, where C denotes the complex number eld. In this case A and ... -
On Statistical Modelling Of Floods And Drought Insurance Products For Developing Countries
(School of Mathematics, 2006)Probabilistic models have been used to measure risk, the chance of occurrence of unfavourable events. The extend of damage may then take the form of a random variable. In this paper we follow such an approach to arrive at ... -
On stock returns volatility and trading volume of the nairobi securities exchange index
(University of Nairobi, 2020)This study attempts to put forward a framework that can be utilized to model the dynamics of the underlying returns on asset. The intention is to probe the dynamic connection between volatility of stock returns and trading ... -
On Support Vector and Relevance Vector Machines
(Centre For Biotechnology & Bioinformatics Publications, 2005) -
On the Accuracy of Quadrature Laplace Transform Inversion and the Solution of State Space Equations
(University of Nairobi.Department of Mathematics, 1978)A quadrature formula is shown to be an approximation of the power-series method of inverting Laplace transforms. This together with the properties of the constants derived from a power-series expansion of the Padé approximation ... -
On the characterization of Class R_1 of non-normal operators in a Hilbert space
(Department of Mathematics, College of Biological and Physical Sciences, University of Nairobi, 2012) -

On The Dual Bishop Darboux Rotation Axis Of The Dual Space Curve
(University of NairobiDepartment of Mathematics, Usak, Turkey, 2000)In this paper, the Dual Bishop Darboux rotation axis for dual space curve in the dual space D3 is decomposed in two simultaneous rotation. The axes of these simultaneous rotation are joined by a simple mechanism.
