A dataset for each nitrosatable component was created with the NBDPS Data Analysis Tools and Database Version 7.04, Medication Exposure Data Set Creation System, that included variables for whether the drug was taken during the first trimester and the number of days taken during that period.
Consider part 1 in Figure 6, the system includes three dependent variables (z1, z2, z3) and two independent variables (z4, z5), and the fluxes contain variables (V +, V−).
It includes variables like "time since Christmas", "weather", "debt level", "motivational levels", "time since failure to keep new year's resolution" and numerous other things that aren't part of the metric system.
This system includes the important staging variables that have survived scrutiny over the years.
The variable structure control system includes a set of controllers that have been prepared and tuned in advance.
A total of 18 coefficients were estimated in the system, including the exogenous variables.
Still, it should be noticed that some scoring systems (i.e., Swiss Diabetes Association) include variables (i.e., familial history) for which the scores were not based upon statistical analysis but on an "educated" proposal by the authors (7).
This research strategy can be successful only if the constituent variables of the system, including the activities of the researcher, are strictly isolated and controlled (= variables manipulation) during the complete examination process.
There are three independent variables in this system including time, breed (pigment), and wound depth.
If such a height-diameter regression model were introduced into the system of simultaneous equations, an integrated biomass equation system including both one- and two-variable models could be developed (Zeng [2013]).
