Since the time to engaging in an activity can in fact be interpreted as duration or the number of times doing each activity, the response variable was then treated as a Poisson random variable but to accommodate over-dispersion the parametric model Negative Binomial was assessed and showed better fit.
Personal 8-h BD exposure measures were made on several occasions over a 60-day period for each potentially exposed worker in order provide maximum accuracy for this independent variable and to accommodate the different expression intervals of the several biomarkers.
For the adoption and transition phases, percent attendance was modeled as the dependent variable; whereas, to accommodate skewness of the untransformed data, a square root transformation was used when modeling frequency of physical activity from the maintenance phase.
A mathematical analysis of some of the static and dynamic properties of dropout is provided using Bernoulli gating variables, general enough to accommodate dropout on units or connections, and with variable rates.
A simple multiplicative latent variable is used to accommodate input uncertainty in rainfall data, enabling a distinction to be made between uncertainty associated with data, parameters and the models themselves.
Also, in both the turbojet and the turbofan with an afterburner, the exhaust nozzle must have a variable throat area to accommodate the large variations in volumetric flow rate between the very hot exhaust stream from the operating afterburner and the cooler airstream discharged from the engine when the afterburner is not in use.
An interesting example is the zero inflated factor analysis (ZIFA), which implements a dimension-reduction approach and uses a latent variable factor model to accommodate zeros [81].
The plates had four variable attachment holes to accommodate specimens of different dimensions, along with four shoulder ball-and-socket joints lead to the four adjustable steel turnbuckles.
PHIST domains, as demonstrated here by PFI1780w (Fig. 6), are characterized by a relatively simple α-helical bundle structure, a type of protein fold that can accommodate divergent sequences and, thus, present variable surface residues to accommodate different binding requirements.
