Categorical variables were described as absolute and relative frequencies and continued variables by the median and as percentiles, minimums, and maximums.
It is clear that the minimization of (35) needs a continues variable w which it is very difficult to be implemented.
A free radical polymerization kinetic mechanism is superimposed into the framework to describe the molecular and morphological polymer properties.The complexity of the kinetic mechanism due to the associated infinite dimensional population balance model (large stiff system of ODEs) is reduced by applying a continues variable approximation scheme over the discrete chain length domain.
The other outcome variable is gestational age, a continues variable.
Cox-regression survival analysis was performed using gene expression signal as continuing variable.
Differences in patients' educational background, gender and age were analysed using logistic regression (with no formal education and male as reference groups; age was used as continues variable).
Factors included in the model were treatment of first breast cancer (radiotherapy (no, yes), chemotherapy (no, yes), endocrine therapy (no, yes)), age at first breast cancer (<50, 50 64 and 65+), year of first breast cancer incidence (continue variable).
When the interest is in using CAC as risk factor for future events (assessment of relative risks), it is most likely that in analyses with CAC as continues variable the magnitude of association of high CAC levels with events reflects an underestimation of the true magnitude.
It means for continues variables, intraclass correlation coefficient (ICCC) absolute agreement single measure should be considered.
We used the t test, with 5% significance level, to check the difference in continues variables.
