The smoothness criterion as a trend diagnostic
The standard approach to time series analysis is to decompose the series into three components, the trend, the seasonal component and the irregular noise. In this paper we are concerned with estimating the trend and so we will assume that all series have been seasonally adjusted. The structural form of the trend is often decided by physical considerations or by inspection of global time series ...
متن کاملA smoothness criterion for monotonicity-preserving subdivision
In this paper we study subdivision schemes that both interpolate and preserve the monotonicity of the input data, and we derive a simple ratio condition that guarantees the continuous differentiability of the limit function. We then show that the condition holds for both a scheme of Kuijt and van Damme, based on rational functions, and a scheme of Sabin and Dodgson, based on square roots. MSC: ...
متن کاملThe Utility of HbA1c as a Diagnostic Criterion of Diabetes
BACKGROUND Hemoglobin A1c (HbA1c) was adopted as a new standard criterion for diagnosing diabetes. We investigated the diagnostic utility of HbA1c by comparing the 2003 American Diabetes Association (ADA) diagnostic criteria of diabetes with HbA1c of 6.5%. Furthermore, the cut-off value for HbA1c was investigated using receiver operating characteristic curves. METHODS This study included 224 ...
متن کاملFructosamine Assay As a Diagnostic Criterion In Thyroid Disorders
Background: Glycation is the process of non enzymatic addition or insertion of sugar to proteins, DNA and lipids. Fructosamine is the generic name for plasma proteins ketoamines; it refers to structure of ketoamine rearrangement product formed by interaction of fructose with ε-amino group of lysine residues of albumin. Its determination monitors the short term glycemic changes and may have a ro...
متن کاملA generalized smoothness criterion for acoustic-to-articulatory inversion.
The many-to-one mapping from representations in the speech articulatory space to acoustic space renders the associated acoustic-to-articulatory inverse mapping non-unique. Among various techniques, imposing smoothness constraints on the articulator trajectories is one of the common approaches to handle the non-uniqueness in the acoustic-to-articulatory inversion problem. This is because, articu...
