Statistical Properties of Construction Duration Data

Beyond the means: validating climate models with higher-order statistics

“…This can be surmounted by mapping s and k to the unit plane using a so-called Θ 1 -Θ 2 representation 12 . This representation discards the sign of the skew parameter, however, which is interesting to retain -are daily temperatures positively skewed or negatively skewed?…”

Risk Evaluation in Road Construction with Neural Networks and Monte Carlo Simulation

“…After analysing some activities of finished project, AbouRizk and Halpin concluded the statistic distribution of activities' duration should be Pearson distribution [10]. Artificial neural networks (ANN) techniques have been applied to solve construction project simulation problems in last years [11][12].…”

A Review of Activity Time Distributions in Risk Analysis

“…Hahn and Martín [10] support the use of a more robust distribution that can accommodate outlying events. An undisputed observation in project management is that most activity time distributions are right skewed [11] [12] [13].…”
