 Derivations And Comparison Of Some Mean Square Errors Of Some Almost Unbiased Ratio Estimators ( Under A Particular Model).

 Adebola,F.B. And Bassey K.J

 2011

Over the years, several ratio type estimators which satisfies the criterion of approximately or almost unbiased ratio estimators have been proposed by several authors. In this paper, the mean square errors of outstanding seven almost unbiased ratio estimators are derived under a particular regression model, and compared to obtain the most efficient among them.

 A Stratified Hybrid Tripartite Randomized Response Technique

 Ewemooje, O.S. ,Adebola, F. B. And ADEDIRAN, A. A.

 2011

This paper proposes a new stratified technique to address the problem involving estimation of the population proportion of people with sensitive attribute(s). Studying the proposed technique under proportional and Neyman allocations shows that the proposed technique is more efficient than (outperforms) the Singh & Gorey [1] and Tarray & Singh [2] stratified randomized response models. Applying the proposed technique to a survey on drug use disorder also shows the applicability of the model

 A Comparative Study Of Some Methods Of Improving Efficiency Of Randomized Response Models

 F.B. Adebola And O Alo Damilola

 2011

This paper compares different randomized response designs by their efficiency condition and also using the concept of Jeopardy Function. A population is divided into two sensitive groups, with unknown proportion , respectively. Considering a dichotomous response model where a typical response R is yes (say, y) or no (say, n). The conditional probabilities that a person R comes from individual of groups, , are , respectively. These probabilities are at the researcher’s disposal and are called Design probabilities. Taking into consideration these design probabilities, a natural measure was proposed and it was carried by , respectively. Considering the Percentage Relative Efficiency of Mangat et al. and Bhargava and Singh, it is found that the Bhargava and Singh model is better than Mangat et al.’s model when and when Mangat et al.’s model is better than Bhargava and Singh’s model

 On The Estimation Of Power And Sample Size In Test Of Independence

 G.M. Oyeyemi, A.A. Adewara, F.B. Adebola And S.I Salau

 2010

In this study, power and sample size estimations in the context of test of independent between categorical variables were examined. The required sample size in an experiment is a function of the alternative hypothesis, the size of type I error and the variability of the population. Power of a test is the probability of rejecting a false null hypothesis and it depends on the effect size, type I error and the sample size. A priori power analysis is determination of minimum sample size to obtain a required power while post-hoc power analysis is calculating power of a test. A test with small effect size requires large sample size to achieve a power 80% or more while effect size of medium or large size needs small sample size to achieve that. Test with small degrees of freedom will attain higher power than the same test with larger degrees of freedom.

 FUTA Enrolment And Graduation Rate: Using Data To Shape Management Decision.

 Bassey, K.J. And Adebola F.B

 2010

Since the inception of the Federal University of Technology, Akure (FUTA), enrolment of students for undergraduate programmes has been on increase regardless of the manning levels. Interestingly, the number of graduates produced increases with the increase in enrolments. Given that not all students enrolled do graduate at the same time, what would be the effect of enrolment reduction on graduates production if management decision to reduce enrolment rate is implemented is the emphasis of this paper. Data from the university are analyzed using covariance analysis to shape management decision.

 A Cost Control Policy For Material Requirements Planning And Procurements

 Bassey, K.J., Adebola, F.B., And Okoro, C.N.

 2010

It is sometimes difficult to predict that a particular material will be out of stock at a particular time. This uncertainty can be avoided by deriving a probability distribution of stock-out. Let us assume that the stock-out of material occur only at the end of certain period, say t. this paper derives a probability distribution theory of stock-out at time t which minimizes the total cost involved for the planning and procurements of material within a production cycle. A control policy to sustain the system when the inventory cost is a function of time with a known depreciation value is presented

 : An Empirical Survey On Poverty, Social Exclusion And Prevalent Disease Pattern In Kogi State.

 Adebola, O.G. And Adebola,F.B

 2008

In order to promote the health of the society, one needs to be in control of the health status determinants. The health status of any society can simply be measured via the study of the pattern of diseases as it relates to social exclusions in the male and female gender. This paper discusses the concepts of social exclusion, poverty and diseases pattern in kogi state with the view of demonstrating the trend of the disease over time. Statistical graphs and charts were employed in this empirical study with Kogi state as a case study. It was discovered that malaria, measles, typhoid fever, pneumonia and diarrhoea are the major threats to health of the people and there exist a positive correlation in both gender across the diseases over time.

 On Application Of Development Of Test Statistic For Testing Unequal Group Variance.

 Kupolusi, J.A. And Adebola, F.B.

 2008

In this paper, an already proposed test-statistic for testing equality of means under unequal population variances is applied. When the group variances differ, using pooled sample variance will give an inappropriate result as a single value for the variances. This kind of problem in statistics is commonly referred to as Brehen-Fisher problem in the k-sample location problems. A proposed unbiased sample harmonic mean of variances 2 H S was examined and found useful for unequal variances which have received a considerable attention in the area of medical and biological sciences. Little or nothing has been achieved in social sciences that form a major part of this work. Data from the six geopolitical zones on road crashes in Nigeria from the year 2004 to 2013 was used to ascertain the consistency of the result with the literature which was found useful and relevant for the proposed developed test statistic. It was observed that using this proposed test statistic, the number of road crashes was significant in some geopolitical zones in Nigeria which was ordinarily latent to pool sample variance

 A Catalyst In The Wheel Of Technological Transformation.”

 2007

ABSTRACT The relevance and role of statistics in theapplications of Technology to every phase of industryinevitably has brought about an increase inmeasurement of every kind. The very fact that this great adventure inmeasurement is of necessity rough, that very often weare unaware of the underlying structure of theuniverse our measurement are sampling is the explanation of why statistical techniques are becomingso widely adopted in technology. The paper tries to explore the place of statistics inupward transformation of technology.
