Table 1. Parameter values and statistical output from best fit models ( Model 0) of the data from Wilcox (1988), Zinaman (1996) and Wang (2003) studies.
Probabilities and percentages were estimated as logits (base 10). Standard errors are shown. Actual probabilities with 95% confidence intervals are reported in Figure 1. Two alternatively parameterised ( Model 0 & Model 00) but statistically identical models were used to obtain standard errors for FEC HCG and FEC CLIN since FEC CLIN = FEC HCG × π CLIN ( ELS = extended least squares; dof = degrees of freedom.)
