Application of factor analysis to data on improved cassava varieties cultivated in Nigeria
This study adopted the multivariate methods to analyze a set of data on the proximate composition of fufu flours processed from 43 different Cassava Mosaic Disease (CMD) resistant varieties from International Institute of Tropical Agriculture (IITA) Onne, Port Harcourt, Nigeria. The factor analysis of the data showed that four components were significant (P <...

Consistent estimators of intrinsically linear econometric model of the Nigerian economy
This study compares the simulation performance of an operational econometric model of the Nigerian economy. Five estimators namely OLS, 2SPC4, 2SPC6 and 2SPC8 were used to obtain consistent estimators of the structural parameters in an econometric model of the Nigerian economy when some of the equations are non-linear but intrinsically linear. The performance of the estimators was ranked...

A note on indirect least squares and matrix partitioning
At times, it is discovered that in using OLS in estimating an equation, inconsistent estimates are obtained because of correlation between the independent variable and the stochastic disturbance term. In such a circumstance, it is likely that the equation so estimated belongs to a wider family of equations related to the practical situation under consideration. Inevitably, a model describing the...

A study on Agile Software Testing: Emergence and techniques
Customer satisfaction, quick and efficient delivery of finished products is all that is needed to lead the way in addressing issues regarding numerous software life cycles. Starting from waterfall model to any present life cycle, we find various advantages and disadvantages to be implemented in software development. Software testing is the state that takes the much of elapse time of SDLC....
