The use of weighted quadratic regression for the study of latencies of the P100 component of the visual evoked potential.
The aim of this study was to determine the range of normal values of the latency of the P100 component of the VEP from a control population. Weighted least squares polynomial regression analysis showed that a quadratic curve best described the relationship between age and latency and separate curves, along with normal ranges, are presented for males and females. We would recommend the use of this statistical method for all determinations of the normal range of P100 latencies.
