Error Calculation or Accuracy Determination DC Measurement Error Type Reading-Dependent Errors Noise and Range-Dependent Errors Specified Accuracy % of reading x reading/100 offset Nonlinearity % nonlinearity x range/100 System Noise rms Peng, Dolores R. Common-Mode Rejection Ratio (CMRR) -- a measure of the capability of an instrument to reject a signal that is common to both input leads. In the latter case, it is often a good idea to use cluster-robust standard errors instead of conventional ones. http://completeprogrammer.net/definition-of/definition-of-specification-error.html

Wilhelm P. Lubinski E. In Bollen, Kenneth A.; Long, J. So, below is a definition with an analogy from a 2005 publication.

Murray D. A classic example in economics is the relationship between years of experience in the labor market (X ) and wages (Y ).

This method results in the most accurate rms value regardless of the shape of the waveform. Geary D. For more information, return to the NI Measurement Fundamentals Main page. Definition Of Specification In Construction This specification is most valuable when you are using the voltmeter to calibrate a device or performing relative measurements.

This sample would not be representative of the general adult population and would influence the data. Data Definition Specification These boards, which are designed for a wide range of applications, are used in a variety of applications from dynamometer control to CD player testing. Lynn R. pp.66–110.

Irwing P. A more general model is which includes the square of X as an additional regressor. Definition Functional Specification We can test whether (1) is correctly specified by using the t -statistic for β 2 = 0, and we can test whether (3) is correctly specified by using the t Definition Design Specification Therefore, this noise is a common-mode signal that is rejected by the CMRR of the instrument.

Schneider J. this content If these assumptions are violated, the parameter estimates may still be unbiased, but confidence intervals and test statistics will generally be incorrect. MacKinnon. 2004. Then, upon analysis, found it to be composed of 70% females. Definition Of Specification In Biology

The reason for this is that the peak nonlinearity error could occur at any point over the full-scale input range. The total accuracy based on the error budget determined above is: Error Type Percent of Reading Errors Range-Dependent Errors Specified Accuracy 1 V x 0.0131% = 131 mV 3 µV Nonlinearity Source Publication: Statistical Policy Working Paper 4 - Glossary of Nonsampling Error Terms: An Illustration of a Semantic Problem in Statistics, United States Federal Committee on Statistical Methodology, 1978. weblink Cognitive markers for across the [email protected],...

People who have moved or are away for the survey period have a higher geographic mobility than the average of the population. Algorithm Definition And Specification We can test whether (1) is correctly specified by using the t -statistic for β 2 = 0, and we can test whether (3) is correctly specified by using the t This model, which is usually estimated by ordinary least squares, could be misspecified in a great many ways.

Referring to equation (4) above, the effective number of digits is: Often, this error is added in the DMM specifications under Percent Range, where the source of the error -- nonlinearity,

pp.442–455. Let us assume a frequency of 1 kHz and a crest factor of 2. The right thing to do in this case would be to estimate (4), not to estimate (1) using a method that corrects for serial correlation. Fda Definition Of Specification Detection[edit] The Ramsey RESET test can help test for specification error.

Although common sense indicates that a 6 1/2 digit multimeter must be accurate to the 6 1/2 digit level, this may not be the case. http://completeprogrammer.net/definition-of/definition-of-rms-error.html Because of the Gaussian distribution of the noise, in this case the effective resolution would be 0.52 ´ 1 mV.
