a normal distribution of data will plot on a chart in a manner that looks like abell-shaped curve. If this standard holds true, then approximately 68% of the expected outcomes should lie between ±1
Assumption of a normal distribution: Many models assume asset returns follow a normal distribution (the bell curve of statistics). However, financial markets often exhibit abnormal behavior, characterized by "fat tails" (more frequent extreme events) and skewness. This can lead to underestimating the...
This factor refers to how closely a laser beam resembles a theoretical Gaussian distribution (or bell curve). Great models can be developed to characterize a beam, but there’s nothing like actually looking at it to assess its profile. Do not mistake what I just said here, even though a ...
