Kredibilitetsintervall
Kredibilitetsintervall, also known as a credible interval, is a concept used in Bayesian statistics to represent a range of values within which an unknown parameter is believed to lie with a certain probability. Unlike frequentist confidence intervals, which are derived from the properties of repeated sampling, credible intervals are probabilistic statements about the parameter itself, based on the observed data and prior beliefs.
In Bayesian analysis, the credible interval is determined from the posterior distribution of the parameter. Given
Credible intervals can be constructed in various ways, such as equal-tailed intervals or highest posterior density
The interpretation of a kredibilitetsintervall differs from classical confidence intervals, as it directly relates to the
Overall, the kredibilitetsintervall is a fundamental concept in Bayesian statistics, providing a probabilistic measure of uncertainty
