The former approach deals with the fluorescence signals of each individual probe and includes background correction, adjustment for the nonspecific signal and expression summary that yields an approximation of RNA abundance or "gene expression," the latter takes the gene expression as an elementary variable [ 11].
The proposed schemes are capable of representing the multivariate stationary stochastic process with a few elementary random variables, bypassing the challenges of high-dimensional random variables inherent in the conventional Monte Carlo methods.
Based on this, a satisfactory simulation accuracy can be guaranteed by selecting a small representative point set of the elementary random variables.
For illustrative purposes, the simulation of horizontal wind velocity field along the deck of a large-span bridge is proceeded using the proposed methods containing 2 and 3 elementary random variables.
9%6%11%12%18%12 % 18 % Elementary Dummy variable, 1 if household head has elementary school as maximum level of formal education, 0 otherwise.
Age was entered in the models as a continuous variable, gender as a dichotomous variable, self-rated health as an ordinal variable (excellent, good, fair and poor), and education as an ordinal variable (elementary, secondary, college, and university including undergraduate and graduate).
(iii) By two elementary changes of variable, t = 1 − x 4, 0 < x < 1 and t = u 30, 0 < u < 1, .
Highest education level attained was available as a categorical variable (elementary school, junior secondary school, high school or university).
A recent approach combines cybernetic variables with elementary flux modes (Young et al. 2008, Kim et al. 2008).
From (6), for every possible value pair of ( X M − n, X M ), we compute the value φ { x, y } = | P ( A B ) − P ( A ) P ( B ) | P ( A ) P ( B ), x, y ∈ Ω, here A, B are the elementary events of random variables ( X M − n, X M ), respectively.
