Empirical Analysis on Road Traffic Crashes in Anambra State, Nigeria: Accident Prediction Modeling Using Regression Approach (Published)

Road traffic crashes in Anambra State Nigeria was considered in this paper, secondary data were mainly used, and was sourced from the office of the Federal Road Safety Corps; Policy, Research and Statistics Department RSHQ Abuja. Regression Analysis was applied on the data, with the aim of identifying how well a set of independent variables (Mechanical Fault, Reckless Driving and Over-Loading) is able to predict Road Accident in Anambra State, indicating, the best predictor of Road Accident in the state, knowing if Overloading is still able to predict a significant amount of the variance in Road Accident when Mechanical Fault and Reckless Driving is controlled for and to develop an accident prediction model. The result shows no violation to the assumptions of Normality, Homoscedasticity, Independence, Linearity, Multicollinearity and Outliers. The three predictors significantly predicted road accident { F(3,9) = 14.132, p-value =0.001 < 0.005 }, R2adjusted= 0.767; 76.7% , of the total variance in road accident cases was explained by the model, Mechanical Fault made the strongest unique significant contribution to explaining road accident cases when the variance explained by all other variables in the model  is controlled for (βeta value = 0.841, p-value = 0.001), Reckless driving made less of a contribution (βeta value =0.591, p-value = 0.004), while overloading did not make a significant contribution to the prediction of road accident when the variance explained by other variables in the model is controlled for (βeta value = 0.173, p-value = 0.228). The developed prediction model is; Number of Road Accident = 6.407 + 1.300Reckless Driving + 1.959Mechanical Fault + 0.733Overloading

The paper attempts to evaluate the relationship between empirical analysis of multinational corporations and economic growth in Nigeria using data spanning (1990-2013). Secondary data was collected from the CBN statistical bulletin and national bureau of statistics. Hypotheses were formulated and tested using time series econometrics and the study reveals that the variables do not have unit roots. There is also long-run equilibrium relationship between economic growth and multinational corporations and the result confirms that about 73% short-run adjustment speed from long-run disequilibrium. The coefficient of determination indicates that about 62% of the variations in economic growth is explained by changes in multinational corporations variables. The study therefore recommends that multinational corporations should make life meaningful to the host country by providing infrastructural facilities. Government should ensure that multinational corporations plough back part of their profits to the development of the host communities in other to established good working relationship. Federal environmental protection agencies should also ensure effective monitoring of multinational corporations to avoid the violation of the lay down rules and regulations guiding their operations.
