Prediction Intervals

Prediction Intervals

The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Propagation of Uncertainty from Systematic Error

Propagation of Uncertainty from Systematic Error

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

Propagation of Uncertainty from Random Error

Propagation of Uncertainty from Random Error

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...

Types of Errors: Detection and Minimization

Types of Errors: Detection and Minimization

Error is the deviation of the obtained result from the true, expected value or the estimated central value. Errors are expressed in absolute or relative terms.
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...

Errors In Hypothesis Tests

Errors In Hypothesis Tests

When performing a hypothesis test, there are four possible outcomes depending on the actual truth (or falseness) of the null hypothesis and the decision to reject or not.

Hindsight Biases

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Area of Science:

Cognitive Psychology
Neuroscience

Background:

Prediction error (PE) is crucial for learning in various domains.
Its role in human one-shot declarative encoding remains less understood.
A hypothesis posits PE reflects divergence between prior and sensory evidence distributions.

Purpose of the Study:

To investigate the role of prediction error in human one-shot declarative encoding.
To test how manipulating prior probability, prior precision, and evidence precision affects memory.
To determine if prediction error enhances the encoding of novel scene-item pairings.

Main Methods:

Five experiments manipulated prediction error factors: prior-evidence distance, prior precision, and evidence precision.
Participants encoded single scene-item pairings after varying prior exposures.
Memory was tested using a three-choice recognition task.

Main Results:

Inconsistent evidence with prior expectations enhanced memory, supporting higher PE.
More precise priors, when inconsistent, led to better memory.
Increased sensory evidence precision also improved memory.
All experiments supported the prediction error hypotheses.

Conclusions:

Prediction error significantly enhances one-shot declarative memory encoding.
The Predictive Interactive Multiple Memory Signals (PIMMS) framework parsimoniously explains the findings.
Findings clarify the role of prediction error in forming new memories.
