Afterwards, the same solutions provided opened many other doors in academic space and one of the applications is in sure probabilities. This research is all about the sure probabilities computed from the zero divided by itself point of view. The solutions obtained in the computations are in harmony with logic and basic knowledge. A wide range of already existing probability distribution functions has been applied in different scenarios to compute the sure probabilities unanimously and new findings have also been encountered along the way. Some of the discrete and continuous probability distribution functions involved are the binomial, hypergeometric, negative binomial, Poisson, normal and exponential among others. It has been found in this work that sure probabilities can be evaluated from the division of zero by itself perspective. Another new finding is that in case of combinatorial, if the numerator is smaller than the denominator, then the solutions tend to zero when knowledge in gamma functions, integrations and factorials is applied. Again, if the case of continuous pdf involves integration and random variable specified in the direction of the parameter, then indirect computation of such probabilities should be applied. Finally, it has been found that the expansion of the domains of some of the parameters in some existing probability distribution functions can be considered and the restriction in conditional probabilities can be revised.</p> Wangui Patrick Mwangi ##submission.copyrightStatement## 2020-01-22 2020-01-22 1 26 10.9734/ajpas/2020/v6i230155 The Beta Type I Generalized Half Logistic Distribution: Properties and Application http://journalajpas.com/index.php/AJPAS/article/view/30156 <p>In a view to obtain a new distribution that is more exible than the type I generalized half logistic distribution, we used the beta-G generator and the type I generalized half logistic distribution. Some properties of the new distribution including the cummulative distribution function,survival function, hazard function were studied. Estimation of parameters were done using the maximum likelihood estimation method. Application of the derived distribution to lifetime data was illustrated by applying to remission times of bladder cancer patient data and survival times of guinea pigs.</p> P. O. Awodutire E. C.

The ARIMA (1,1,1) model and neural network with architecture (6:1:3) turns out to be the most fitted among the considered models, these models were used for forecasting the returns, and their performances have been compared according to some statistical measure of accuracy. A hybrid model has been constructed using ARIMA-Artificial Neural Networks model, the computational results on the data reveal that the hybrid model using Artificial Neural Network, provides better forecasts, and will enhance forecasting over the single ARIMA and Artificial Neural Networks models. The study recommends the use of ARIMA-Artificial neural network for modelling and forecasting stock market returns.</p> Yakubu Musa Stephen Joshua ##submission.copyrightStatement## 2020-01-24 2020-01-24 42 53 10.9734/ajpas/2020/v6i230157 ARIMA Modelling of Neonatal Mortality in Abia State of Nigeria http://journalajpas.com/index.php/AJPAS/article/view/30158 <p>In this study, the incidence neonatal mortality in Abia State of Nigeria was considered<br>using data from January 2014 to December 2018. The data was obtained from the Federal<br>Medical Centre, Umuahia in Abia State of Nigeria. The time plot of the data and the ADF<br>test conducted conrmed the series to be stationary. The plots of the ACF and PACF cut<br>o after lags 4 and 1 respectively which suggested ARIMA (1, 0, 4). However, diagnostic<br>checks led us to select ARIMA (1, 0, 1) as the best model to t the data and it was used to<br>make forecast. Our forecasted values indicate there will be a continous decline in the incidence<br>of neonatal mortality in Abia State of Nigeria. Much should be done to even expedite the decrease.</p> C.
