The SAO non-linear optimization has the capability to adjust continuous and discrete variables
to define a complex system.
The final set of chi-square tests of independence evaluated the relationship between animal cruelty and each discrete variable
of parental abuse.
The first version uses discrete variables
, while the second version uses continuous variables.
These variables can be divided into two categories as continuous variables and discrete variables
. Actually, in practical engineering applications, discrete variables
are used commonly as design or optimization variables, cross-sectional areas of the structural members, for instance.
The purpose of a Parametrized Correlation Method is to determine a relationship between two sets of stochastic discrete variables
. In statistics, the "correlation" concept has a very specific meaning.
The dependent variable of the ordered probit model is a discrete variable
and only contains three values (-1,0,1).
Equation (3) shows the impedance analysis cupping to ensure system stability as Re (1/Zc1) and admittance Y * as a discrete variable
The random variables are considered to be continuous but the discrete variable
case could be treated similarly.
Cavicchi in , its result being presented in theorem 1 from Section 2 in continuous variable case and in theorem 2 from Section 3 in discrete variable
Comparison with IABC with DE, G3-GA  and MABC for Reconfigurable Antenna-array Design with Discrete Variable
So, the time can also be a discrete variable
, and the state space can also be discrete.
where E is the shift operator of the discrete variable
n, defined by [E.sup.k] f(n) = f(n + k), k [member of] Z; t and y are continuous variables, [a.sub.1], [a.sub.-1], [b.sub.-1], [[alpha].sub.1], [[alpha].sub.2], [[beta].sub.1], and [[beta].sub.2] are functions of t and y.
