The quintile analysis is performed similarly to the octile
methodology of Hendricks et al.
Adjusted least square means for SBP and DBP estimated for each octile of AChE activity were closely aligned with the estimated linear trends, thus providing visual evidence of good model fits (Figure 1).
In addition we plotted the association of blood pressure as a linear function of AChE and adjusted least square mean estimates for SBP and DBP according to octiles of AChE activity to visually assess model fit.
Brown and Goetzmann (1995) find that funds in the bottom octile
show significant negative persistence, while funds in the top octile
show non-significant positive performance persistence.
For example, we received responses from 21 of the 39 firms in the top octile

077) With separate octile effects added (p-value for indicated [H.
We split the observed homestead exemption rates into octiles, each with 50 observations, and estimate the model with the first octile omitted to avoid perfect collinearity.
