Statistical Model of Extreme Values In Vehicular Emission

olubiyi adenike Olubiyi, O. E. Olubusoye

Abstract


This paper presents work on the application of Gumbel distribution for evaluating extreme values in vehicular emission using data from six different locations in Ogun State, Nigeria. The daily emission data were obtained using Kane Gas Analyser for collection from 2008-2011. The exploratory data analysis tools used reveals the presence of extreme values in the data and also the data set was found to exhibit positive skewness. The Quantile-Quantile plot and probability plot was plot to test for the adequacy of the distribution and the two plots indicate that Gumbel distribution fits the data.


Keywords


Extreme values; Generalized Extreme Value Distribution; Boxplot; Matrix plot; Beta-distribution.
