Abstract:

This study investigates the Unreplicated Linear Functional Relationship (ULFR) model where the measurement error term, δ, is introduced. The coefficient of determination (COD) of ULFR, denoted by R2f is proposed and it properties are investigated. When the introduction of δ increases significantly the COD, we say that the causation factor has been incorporated into the independent variable. Present result on the Malaysian road accident data illustrates the causal relationship between the socio-biological factors and road accident may be explained.
