Confidence Interval
A confidence interval is a range of values, derived from sample statistics, that is likely to contain the value of an unknown population parameter, with a specified level of confidence.
Alpha (α)
In investing, alpha represents the excess returns of a portfolio relative to the return of a benchmark index. In statistics, it often denotes the level of significance in hypothesis testing.
Confidence Level
It describes the degree of certainty associated with a statistical estimate or range, typically expressed as a percentage, indicating how likely it is that the true value lies within a specified interval.
Confidence Interval
A range of numbers, derived from statistical analyses of samples, likely to possess the value of a population parameter that remains unknown.
