Introduction: The all the time use of linear computer-based test for ability estimation in Africa could be traced to inadequate knowledge computerized adaptive testing arrive at a precise estimate examinee. Purpose: purpose search work was explain method which is one grey areas researchers whose interest are on testing. Findings: This paper discussed Maximum Likelihood Estimation method, provid...

In this article, we propose an intersection-union test for multivariate forecast accuracy based on the combination of a sequence univariate tests. The testing framework evaluates global null hypothesis equal predictive ability using any number tests under arbitrary dependence structures, without specifying underlying distribution. An extensive Monte Carlo simulation exercise shows that our prop...

in this study we have tested the ability of a standard dft computational protocol to reproduce the experimentally obtained stereoselectivity of 26 different c2-symmetric zirconocene catalysts active in propylene polymerization. the catalysts were chosen for their relevance in metallocene catalyzed polymerization of propylene. to this end, primary insertion of both si- and re-propylene enantiofa...

This paper employs Adaptive Neuro-Fuzzy Inference System (ANFIS) to predict water level that leads to flood in coastal areas. ANFIS combines the verbal power of fuzzy logic and numerical power of neural network for its action. Meteorological and astronomical data of Santa Monica, a coastal area in California, U. S. A., were obtained. A portion of the data was used to train the ANFIS network, wh...
