Thus, we used a coalescent model that incorporates exponential growth with rate parameter α = 7 (Slatkin and Hudson 1991).
Rate distortion models including power model, exponential model, and the proposed combining the power and exponential models are studied.
We tested the hypothesis that breakdown would be fastest in relatively warm and moist aerobic environments by comparing the time required for 50% loss of initial ash-free dry matter (T50) calculated using exponential decay models incorporating a lag term.
The model incorporates the effects of bearing geometry, shaft speed, bearing load distribution, transfer function and the exponential decay of vibration.
This model incorporates an additional parameter (in Eq. 10), which regulates the transition between the initial exponential phase and the growth-saturated phase (a small will result in a smooth transition).
So our model incorporates direct interaction.
They also allow the comparison between models incorporating gamma distributed infectious sojourn times (with exponential distributed and constant infectious periods are the two extremes) with equal means and with different variances.
Clearly, models incorporating more biology and possessing more general growth patterns than exponential or Gompertz dynamics are required to explain such phenomena.
*ROC regression models incorporating age as covariate.
