Probability of error
open-in-new
<p>In <a href="/facts/Statistics/DNPsKGYU">statistics</a>, the term "error" arises in two ways. Firstly, it arises in the context of <a href="/facts/Decision_making/NbJYprSw">decision making</a>, where the probability of error may be considered as being the probability of making a wrong decision and which would have a different value for each type of error. Secondly, it arises in the context of <a href="/facts/Statistical_modelling/jKkT5ftm">statistical modelling</a> (for example regression) where the model's predicted value may be in error regarding the observed outcome and where the term probability of error may refer to the probabilities of various amounts of error occurring. </p>
