Uncertainty in Measurement: Accuracy and Precision03:37

Uncertainty in Measurement: Accuracy and Precision

73.6K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Uncertainty: Overview

550
In analytical chemistry, we often perform repetitive measurements to detect and minimize inaccuracies caused by both determinate and indeterminate errors. Despite the cares we take, the presence of random errors means that repeated measurements almost never have exactly the same magnitude. The collective difference between these measurements - observed values - and the estimated or expected value is called uncertainty. Uncertainty is conventionally written after the estimated or expected value.

The Uncertainty Principle

23.3K
Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

Propagation of Uncertainty from Random Error00:59

Propagation of Uncertainty from Random Error

679
An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

Econometric Views (EViews)

138
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

Random and Systematic Errors01:20

Random and Systematic Errors

10.9K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Summary

Economic policy uncertainty (EPU) negatively impacts financial system efficiency (FSE), including financial institution efficiency (FIE) and financial market efficiency (FME). High EPU periods exacerbate these adverse effects, requiring policy attention.

Area of Science:

  • Economics
  • Finance
  • International Finance

Background:

  • Economic policy uncertainty (EPU) poses risks to global economies and corporations.
  • Financial system efficiency (FSE) is crucial for economic growth, yet the impact of EPU on FSE is under-researched.

Purpose of the Study:

  • To investigate the effect of EPU on FSE, including its components: financial institution efficiency (FIE) and financial market efficiency (FME).

Main Methods:

  • Analysis of data from 22 countries spanning 2002-2021.
  • Utilized two-stage least squares and two-step dynamic system generalized method of moments estimators.
  • Conducted sensitivity tests with alternative measures and control variables.

Main Results:

  • A significant negative relationship was found between EPU and FSE, FIE, and FME.
  • Split-sample analysis revealed that adverse effects of EPU are more pronounced during high-EPU periods.

Conclusions:

  • Elevated economic policy uncertainty detrimentally affects financial system efficiency.
  • Policymakers should monitor and manage EPU to safeguard financial system functioning and economic stability.
