Repeated measurements in stochastic mechanics
Physical Review D, 1986Stochastic mechanics provides a probabilistic scheme for the description of quantum systems. Grabert, Haaumlnggi, and Talkner, and Nelson have pointed out that its multitime correlations seem to be in disagreement with quantum-mechanical predictions.

Repeated measurements: What is measured and what repeats?
Statistics in Medicine, 1990AbstractThis paper expresses a personal view of experiments involving repeated measurements; it attempts to classify types of experiment and approaches to statistical analysis: no novel procedures are proposed, only a systematic outlook on objectives and methods.

Repeated Measurements with the Wisc
Psychological Reports, 1962An examination was made of scores obtained on the WISC with repeated measurements of the same population. Ss were 65 educable mentally retarded boys. They were all male residents at the Training School who had been given the complete WISC at least 3 times.

Im Unterschied zu den vorausgegangenen Kapiteln nehmen wir an, das an einem Objekt/Subjekt (z.B. Patient) nicht nur eine Beobachtung vorgenommen wird, sondern das wiederholte Beobachtungen vorliegen. Diese wiederholten Messungen (repeated measures oder repeated measurements) werden zu vorher definierten Zeitpunkten erhoben und sollen Auskunft geben ...

Repeatability of sonographic measurements in clubfeet
Acta Radiologica, 2004Purpose: To assess the intra‐ and interobserver agreement of ultrasound assessment of clubfoot patho‐anatomy in early childhood. Material and Methods: Seventeen clubfeet in 12 children were sequentially scanned by 2 examiners and repeat assessments were carried out independently.

Heterogeneous Variances in Repeated Measures
Biometrical Journal, 1995AbstractA general approach to repeated measures analysis described in MCGILCHRIST and CULLIS (1991) is extended to general linear models in which there is a homogeneous correlation structure such as a stationary process but the variances are heterogeneous over time.

The Repeatability of Corneal Thickness Measures
Cornea, 2000To compare the repeatability of three measures of corneal thickness: Orbscan Slitscan pachymetry, ultrasound pachymetry, and optical pachymetry.Twenty normal subjects were tested on three occasions. Two occurred on the same day and the third was on a different day at approximately the same time of day as one of the first two visits.

Abstract In this chapter, we discuss methods for analysing data which consist of a number of relatively short non-stationary time series in which the trends, µ;(t) say, are of direct interest. This situation arises in experiments which involve comparisons amongst trends associated with different treatments (cf. Examples 1.6, 1.7).

Repeatability of Ocular Wavefront Measurement
Optometry and Vision Science, 2003ABSTRACT: Purpose. To assess the repeatability of measurements of ocular aberrations using wavefront sensing in a small group of observers and to assess the potential effect of measurement error on custom corneal correction due to this variability.

The repeatability of corticomotor threshold measurements
Neurophysiologie Clinique/Clinical Neurophysiology, 2004Threshold (Th) is a neurophysiological parameter frequently used in TMS studies. The present study was designed to investigate the repeatability of the Th measurements by reexamining healthy subjects over various time points. Overall, 82 subjects (median age: 19 years, range: 12-65) entered the study.
