Abstract The authors propose a VN,p test statistic for testing finite-order serial correlation in a semiparametric varying coefficient partially linear errors-in-variables model. The test statistic is shown to have asymptotic normal distribution under the null hypothesis of no serial correlation. Some Monte Carlo experiments are conducted to examine the finite sample performance of the proposed...

Assessing agreement is often of interest in clinical studies to evaluate the similarity of measurements produced by different raters or methods on the same subjects. Lin's (1989, Biometrics 45, 255-268) concordance correlation coefficient (CCC) has become a popular measure of agreement for correlated continuous outcomes. However, commonly used estimation methods for the CCC do not accommodate c...
BACKGROUND In chronic Chagas disease (ChD), impairment of cardiac autonomic function bears prognostic implications. Phase‑rectification of RR-interval series isolates the sympathetic, acceleration phase (AC) and parasympathetic, deceleration phase (DC) influences on cardiac autonomic modulation. OBJECTIVE This study investigated heart rate variability (HRV) as a function of RR-interval to ass...
BACKGROUND/AIM This study examined the reliability and convergent validity of the Writing Readiness Inventory Tool in Context, a measurement evaluating writing readiness in kindergarten children (aged from five to six years). METHODS Test-retest reliability was established with 59 children, inter-rater reliability with 72 children and convergent validity with 119 children. All participants we...
