"Every ad features models age 16 to 22 with a blank stare, when the real consumer in luxury fashion stores is more like 35 to 65," he said.
"When it comes to older models, age is less important than how well the car's been maintained".
In the above age-structured predator prey population models, age structure is introduced into interactions of multi-species, and population models can quickly become remarkably complex [7, 13].
The following variables were incorporated into the primary multivariable models: age, the presence of rigor ('shaking chills'), prior location to the ICU, and chronic health condition with immunosuppression.
In the development of the prognostic models, age at diagnosis (number of years), radiological stage (stage IA-IV) and treatment (curative vs palliative) were included because these are strong predictors of survival [26].
In animal models, age was found as a factor of thickness and integrity of the vaginal epithelium [42].
The following set of variables were included in all models: age at enrollment, race, gender, age at first rubella vaccination, age at second rubella vaccination, and cohort status (first versus second).
Multiple logistic regression models for MSI status were also evaluated in the subset of the data in which there were no missing values for all of the variables included in the models (age, MSI, IHC, methylation, and three SNPs).
In all models, age, sex, survey year, years of full-time education, being in paid employment, and net household income in the last year prior to the survey were included as covariates.
For multivariable models, age was always retained.
In all models age was an independent variable.
