Values of the parameters of the selectivity logistic curves
, selectivity size, and selectivity interval for male and female crabs.
The standard model still could be applicable because the increase in skipped spawning occurred at younger ages (4-15), the logistic curves
reached 100% around age 12 (close to age 15), and fish commonly reach ages >50.
3) The cumulative probability distribution of failure of the electrical components in distribution networks summarized in  is consistent with logistic curves
Results of the LSDM performance with observed scores on individual attributes shows that the APCs recovered with LSDM match well the ICCs of individual items for operations A1 and A2 but for A3 A4 and A5 the APCs tends to be over the ICCs on all the ability levels; these results may be explained by the conjunctive nature of the model, moreover, the product of logistic curves
is not logistic, for this reason this work presents a descriptive and exploratory explanation, more than a statistical comparison between curves.
Sigmoid (S) shaped or logistic curves
predict the carrying capacity which is the population that is sustainable in an environment.
Furthermore, the logistic curves
all show a relatively flat peak, with a pronounced "hang time" near the peak.
The field data for BegShed, MaxShed, EndShed, and Silking of each treatment population were fit to standard logistic curves
of the form:
In situations where there is little to gain from departures from standard and well-understood model specifications, my preference in modeling real-world phenomenon has always been to work with such specifications, such as the Gompertz and logistic curves
The Gompertz and logistic curves
are the two most widely used specifications of S-curves.
Table 1 shows parameter values of logistic curves
fitted to derived h prior distributions as natural mortality (M) ranged from 0.
, derived from the prevalence of mature male P.
Using an estimated split model (Millar and Walsh, 1992), we fitted logistic curves
to these data by maximum likelihood method (Pope et al.
