Spectroscopic approaches for conformity analysis of e-liquids
modelling. Next to baseline correction, classical preprocessing techniques like standard normal variate (SNV), derivatives and scaling were explored. In a first step, supervised modelling, using partial least ...
A new approach to define acceptance limits for hematology in external quality assessment schemes.
their corresponding assigned value (U-scores) was modeled by means of an adaptation of Thompson’s “characteristic function”. Quantile regression was used to investigate the percentiles of the U-scores for ...
Advanced Methods for Dose and Regimen Finding During Drug Development: Summary of the EMA/EFPIA Workshop on Dose Finding (London 4-5 December 2014).
for drug developers and regulators were presented. These methods are described in the present report: they include five advanced methods for data analysis (empirical regression models, pharmacometrics ...
Zona pellucida gene mRNA expression in human oocytes is related to oocyte maturity, zona inner layer retardance and fertilization competence.
main predictor of the fertilization capacity, next to IL-retardance and IL-thickness. Using stepwise regression analysis, IL-thickness combined with EFNB2 expression in CC and the patient’s ovarian ...
Childhood leukaemia near nuclear sites in Belgium, 2002-2008.
acute leukaemia among children aged 0-14 years living in the vicinity of the nuclear sites in Belgium. Poisson regression modelling was carried out for proximity areas of varying sizes. In addition, the ...
ATR-FTIR spectroscopy and chemometrics: An interesting tool to discriminate and characterize counterfeit medicines.
Regression Trees (CART) and Soft Independent Modelling of Class Analogy (SIMCA). First it was verified whether the mentioned techniques are capable to distinguish samples containing different active ...
Headspace-gas chromatographic fingerprints to discriminate and classify counterfeit medicines.
Principal Component Analysis, Projection Pursuit, Classification and Regression Trees and Soft Independent Modelling of Class Analogy. It was tested whether these techniques can distinguish genuine ...
Classification trees based on infrared spectroscopic data to discriminate between genuine and counterfeit medicines
method methods MODEL models ON Order public public health Public-health regression Sample Samples System Technique use world Abstract: Due to the extension of the internet, counterfeit drugs represent ...
A new statistical method for evaluating long-term analytical performance of laboratories applied to an external quality assessment scheme for flow cytometry.
RESULTS: The model was applied to the results obtained by 52 laboratories for CD4 %. From the 1340 data points, 35 were determined to be regression outliers. The second step revealed one regression line with ...
