On the efficiency of testing procedures in the linear model for multivariate longitudinal data
(School of Biological Sciences, 2011)Multivariate data collected over time on the same experimental unit, referred to as multivariate longitudinal data, are typical of many agricultural, biological, clinical and medical studies. One way to account for the ... -
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 ... -
