When does a function have an extreme value?
The Extreme value theorem states that if a function is continuous on a closed interval [a,b], then the function must have a maximum and a minimum on the interval. This makes sense: when a function is continuous you can draw its graph without lifting the pencil, so you must hit a high point and a low point on that interval.
How to find the max value with conditions?
To find the max value when any of the specified conditions is met, use the already familiar array MAX IF formula with the Boolean logic, but add the conditions instead of multiplying them. As an example, let’s work out the best result in rounds 2 and 3.
When does the extreme value theorem apply to an interval?
In short: the extreme value theorem only applies when the function is continuous on an interval that is both closed and bounded (well, strictly speaking, the function need not be defined on an interval, its domain need only be compact.)

When to use brackets in the extreme value theorem?
So the extreme value theorem says if we have some function that is continuous over a closed interval, let’s say the closed interval from a to b. And when we say a closed interval, that means we include the end points a and b. That is we have these brackets here instead of parentheses.
Which is the best description of extreme value theory?
Statistical extreme value theory is a field of statistics dealing with extreme values, i.e., large deviations from the median of probability distributions. The are the iid expected values of the order statistics from the normal distribution and V represents the covariance matrix of these order statistics.
Which is an example of an extreme value distribution?
Extreme value distributions are the limiting distributions for the minimum or the maximum of large collections of independent random variables from the same arbitrary distribution. By definition extreme value theory focuses on limiting distributions (which are distinct from the normal distribution).
