In this research, the formation of second derivative two-step block hybrid Enright’s linear multistep methods for solving initial value problems is studied. In forming the method, we follow Enright’s 1974 approach, by introducing the off-mesh points at both interpolation and coll...

According to Cobham’s thesis, computational problems can be practically (or, in other words, feasibly) computed on some computational device only if they can be computed in polynomial time. Despite the presence of many objections to this claim, they are all not decisive. Then aga...

It is imperative to analyze educational data especially as it relates to students’ performance. Educational institutions need to have a fairly accurate knowledge of admitted students’ prior academic ability to predict their future academic performance. This helps to identify the...

Clustering is an unsupervised method where the number of clusters is not known by users. Therefore, the outcomes of a clustering algorithm depend on the input number of clusters specified by users. Consequently it is very important to evaluate the result of the clustering algorit...

It is not uncommon to encounter data where the distribution of the responses is not known to completely follow any of the common probability models. While there are general classes of models, such as the Tweedie distribution, which can be adopted in such cases, many approximation...

A formula for the confidence interval of correlation coefficient based on the Fishers’ z-transformation, (where z = arctanh(r) and is used to convert the skewed distribution of sample correlation, r to a normal distribution) was applied to the age and systolic blood pressure of 2...
