Standard error – Wikipedia – The standard error (SE) of a statistic (most commonly the mean) is the standard deviation of its sampling distribution, or sometimes an estimate of that standard.
What is ‘Regression’ Regression is a statistical measure used in finance, investing and other disciplines that attempts to determine the strength of the relationship.
