The mathematical correlations and regression assessment led to the derivation of simple polynomial expressions which were used for sensitivity analysis and may be useful for the design, monitoring and control of this important desalination process.
Although the beta estimate from the multi-variable regression assessment of methemoglobin levels at 36 weeks was suggestive of higher methemoglobin levels among pregnant women with higher estimated nitrate intake from tap water, it was not statistically significant (β = 0.046, p = 0.986) (Table 7).
Meta-regression assessments of factors possibly affecting PM10-term LBW associations indicated that heterogeneity was influenced by median PM2.5 exposure levels, the PM2.5 PM10 ratio, and the applied exposure contrast (temporal vs. spatiotemporal).
For Poisson data and log-linear regression, similar assessments are made using maximum likelihood and the Akaike information criterion for minimally-supported designs that are constructed analytically.
This article discusses areas of controversy and difficulty regarding the evaluation of the extent of residual tumour tissue, grading of tumour regression and assessment of the margins, and explains the important clinical implications of the present uncertainty and divergence in pathology practice.
The logistic regression and assessment of significance was performed in Genstat v16.
Key words were predict, screen, risk, score, [type two] diabetes, model, regression, risk assessment, risk factor, calculator, analysis, sensitivity and specificity, ROC and odds ratio.
We did not have adequate numbers of cases to conduct regression-based assessments of trends, thus we calculated 95% CI and tested whether the changes between time period-specific rates were statistically significant, treating 2000-2002 as the reference group, using a z score [ 19].
These include: a disorder of movement or posture of central origin, a disorder of motor function, no evidence of clinical regression, latest assessment at 4 years of age or older, absence of syndrome/brain anomaly/chromosomal anomaly and no evidence of generalized hypotonia.
It includes three stages: (1) simulation of short wave infrared bidirectional reflectances of a "reference scene" with constant architecture and variable chemistry; (2) establishment of predictive relationships of chemicals with stepwise regressions; (3) assessment of the robustness of these relationships for scenes with variable structures.
Based on the parametric assessments, regression models are proposed for predicting the global and storey drifts.
