Assessment of various probability distributions to model Pm 10 concentration for industrialized area in peninsula Malaysia: a case study in Shah Alam and Nilai
(AENSI Publications, 2011-12)In Malaysia, the predominant air pollutants are suspended particulate matter (SPM) and nitrogen dioxide (NO 2). This research focused on PM10 as they may trigger harm to human health as well as environment. Six distributions, ... -
Estimation of missing values in air pollution data using single imputation techniques
(Science Society of Thailand, 2008)Air pollution data obtained using automated machines often contain missing values which can cause bias due to systematic differences between observed and unobserved data. We used interpolation and mean imputation techniques ... -
Mean imputation techniques for filling the missing observations in air pollution dataset
(Trans Tech Publications, 2014)Almost all real life datasets consist missing values. These are usually due to machine failure, routine maintenance, changes in siting monitors and human error. The occurence of missing values requires special attention ... -
