term (ϵ — β_3*δ) is also normally distributed around a zero mean and it has a variance of (σ²_ϵ + β²_3*σ²_δ). The effects of measurement error in the regression variables on the model The variance (σ²_ϵ + β²_3*σ²_δ) of the composite error of the model in Eq (6) suggests the following effects on the
