ABSTRACT
This chapter discusses the research conducted by Price Associates, Inc. (PAI) that addressed the effects of measurement error in statistical analysis of relationships between Lead in household dust (PbD), lead-based paint (LBP), and other variables that are potential sources of Pb exposure. PbD, lead in soil (PbS), and LBP have been noted as the most direct sources of Pb causing elevated blood levels in children. PAI that addressed the effects of measurement error in statistical analysis of relationships between PbD, LBP, and other variables that are potential sources of Pb exposure. Housing and Urban Development (HUD) provides tables showing national estimates of DUs with LBP above the HUD limit of 1 mg/cm and PbD above the HUD Pb concentration limits for household dust. In regression analysis, which is one of the primary statistical methods used for assessing sources of Pb, ignoring measurement error may result in biased estimates of regression coefficients.
