Correlation for prediction

Clinical assessment of functional disability is an integral part of management in patients with low back pain (LBP). The range of spinal motion is one of LBP disability measure. The aim of this study was to investigate the validity of spinal range of motion as a predictable measure of disability and to analyze the intrarater reliability of back range of motion (BROM) instrument for measurement of active lumber spine range of motion. Forty men patients with chronic low back pain over 6 month’s duration were participated in the study. Their ages ranged from 20 to 40 years.

Peng–Robinson equation of state is widely used with the classical van der Waals mixing rules to predict vapor liquid equilibria for systems containing hydrocarbons and related compounds. This model requires good values of the binary interaction parameter kij. In this work, we developed a semi-empirical correlation for kij partly based on the Huron–Vidal mixing rules. We obtained values for the adjustable parameters of the developed formula for over 60 binary systems and over 10 categories of components.

Various parameters have been considered for predicting survival in pancreatic ductal adenocarcinoma. Information about western population is missing. The aim of this study is to assess the association between Glucose transporter type 1 (GLUT-1) expression and prognosis for patients with PDAC submitted for surgical resection in a European cohort.

It has been shown that the deregulation of miRNAs is associated with the development and progression of many human diseases. To reduce time and cost of biological experiments, a number of algorithms have been proposed for predicting miRNA-disease associations.

An organism’s protein interactome, or complete network of protein-protein interactions, defines the protein complexes that drive cellular processes. Techniques for studying protein complexes have traditionally applied targeted strategies such as yeast two-hybrid or affinity purification-mass spectrometry to assess protein interactions.

The rationale for selecting three cardinal symptoms is based on their high sensitivity and their relatively high specificity for ABRS, especially when considering the time interval of persistence for 10 days or longer. 36-38 Purulent nasal drainage predicts presence of bacteria on antral aspi- ration when reported as purulent rhinorrhea by the patient, when manifest as postnasal drip or purulent discharge in the posterior pharynx, or when observed in the nasal cavity or near the sinus ostium. 39,40 Purulent rhinorrhea also predicts radiographic evidence of ABRS.

Based on the discussion of contracting's implications for earnings calculation, we model operating cash flows and the formal accounting process by which forecasted future operating cash flows are incorporated in earnings. The modeling enables us to generate specific integrated predictions for: i) the relative abilities of earnings and operating cash flows to predict future operating cash flows; and ii) firms' time series properties of operating cash flows, accruals and earnings. We also predict cross-sectional variation in the relative forecast-abilities and correlations.

We compare the predicted values with actual correlations for the sample firms and investigate the cross-sectional relation between them to assess the extent to which the simple model described in the previous section fits the data. First, we report the average values of the predicted serial-and cross-correlations among earnings changes, operating cash flow changes and accrual changes.

Consider the family of sensor routing protocols where each sensor communicates either directly or indirectly with a base station. In turn the base station correlates and aggregates information from each sensor. Accordingly, the base station will need to verify the authenticity of the sensor, the integrity of the communication and ascertain that it is not a replay of an earlier communication. Recall the assumption that the base station is computationally robust and secure. In our protocol each sensor j shares a unique 64 bit Key Key , with the base station.

In contrast to many languages (like Russian or French), modern English does not distinguish formal and informal (“T/V”) address overtly, for example by pronoun choice. We describe an ongoing study which investigates to what degree the T/V distinction is recoverable in English text, and with what textual features it correlates. Our findings are: (a) human raters can label English utterances as T or V fairly well, given sufficient context; (b), lexical cues can predict T/V almost at human level. ...

Different summarization requirements could make the writing of a good summary more difficult, or easier. Summary length and the characteristics of the input are such constraints influencing the quality of a potential summary. In this paper we report the results of a quantitative analysis on data from large-scale evaluations of multi-document summarization, empirically confirming this hypothesis.

Sentence fluency is an important component of overall text readability but few studies in natural language processing have sought to understand the factors that define it. We report the results of an initial study into the predictive power of surface syntactic statistics for the task; we use fluency assessments done for the purpose of evaluating machine translation. We find that these features are weakly but significantly correlated with fluency. Machine and human translations can be distinguished with accuracy over 80%.

The intermolecular interaction potentials of the dimer H2-O2 were calculated from quantum mechanics, using coupled-cluster theory CCSD(T) and correlation-consistent basis sets aug-ccpVmZ (m = 2, 3); the results were extrapolated to the basis set limit aug-cc-pV23Z. The quantum mechanical results were used to construct 5-site pair potential functions. The cross second virial coefficients of the dimer hydrogen-oxygen were obtained by integration; in these cases corrections for quantum effects were included. The results agree well with experimental data and empirical correlations.

Concerns over reliability assessments of the main components in nuclear power plants (NPPs) related to aging and continuous operation have increased. The conventional reliability assessment for main components uses experimental correlations under general conditions. Most NPPs have been operating in Korea for a long time, and it is predictable that NPPs operating for the same number of years would show varying extent of aging and degradation.

The reliability of Quantitative Structure – Activity or Property Relationships for prediction of physico-chemical properties and anticancer activity of flavone and isoflavone derivatives was improved by using the quantitative relationships between structurally similar flavone and isoflavone structures (QSSRs). The targeted-compound method was developed by a training set, which contains only similar compounds structurally to target compound.
