COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
corrected for time shifts using correlation optimized warping and further pretreated using classical techniques like signal noise variate, autoscaling and derivatives), before being subjected to partial least ...
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 ...
Rational arguments for regulatory acceptance of consistency testing: benefits of non-animal testing over release testing of vaccines.
techniques to measure critical quality attributes. However, introduction of in vitro alternatives to replace in vivo release assays of authorized vaccines is challenging. AREAS COVERED: This report describes ...
Using random-forest multiple imputation to address bias of self-reported anthropometric measures, hypertension and hypercholesterolemia in the Belgian health interview survey
compared with multiple imputation by chained equations based on parametric and non-parametric techniques. RESULTS: This study confirmed the underestimation of risk factor prevalence based on self-reported ...
