In recent comparisons among several techniques of algorithms and predictions of species distributions, MaxEnt ranked as the best-performing model using presence-only data and showed a better performance comparable to 16 other algorithms, including several traditional tools using presence-absence data, such as general linear models (GLM) and general additive models (GAM) [69].
However, in the absence of relevant data, such assumptions can only be speculative.
Overall, results of this study suggest that topographic maps provide a useful source for determining long-term change in imperviousness in the absence of suitable data, such as remotely sensed imagery.
In the absence of empirical data, such effects have been forecast using models [6] [8] parameterized from observations of natural and experimental prion infections in captive deer [4], [8] [10].
A second limitation is the absence of individual data such as maternal age, marital status, previous births, parental occupation, and smoking habits.
However, in the absence of empirical data, such extrapolations depend heavily on assumptions regarding the exposure-response relationship at the lowest levels of exposure.
This registry study had certain limitations due to the absence of preoperative data such as VAS, HAD, and ROM, which was the reason for using a matched control group.
The biological significance of fold changes in gene expression between control and OA samples is unknown in the absence of additional data such as gross, radiographic, or histological scoring or protein quantification.
However, in the absence of patient data such as height and weight, estimation of kidney function by established equations becomes less accurate for individuals below 18 years of age, and we did not consider them in our analyses.
A number of recent guidelines recommend switching an antipsychotic drug to an agent with a less deleterious effect on metabolic function in patients who develop hyperglycaemia or experience significant weigh gain [ 8, 9, 14], but in the absence of longitudinal data, such strategies lack a firm evidence base.
