Documentation/How Tos/Calc: KURT function

KURT

Returns a measure of how peaked or flat a distribution is.

Syntax:

KURT(number1; number2; ... number30)

number1 to number30 are up to 30 numbers or ranges/arrays containing numbers.

KURT returns the kurtosis, a measure of how peaked or flat a distribution is, relative to a normal distribution. Positive values indicate a relatively peaked distribution, and negative a relatively flat distribution. KURT calculates:

for the n >= 4 numbers having a standard deviation s > 0.

Example:

KURT(A1:A30)

returns the kurtosis of the numbers in A1:A30.

KURT(1; 3; 4; 5; 7)

returns 0.2, indicating that this (too small to be useful) distribution is slightly peaked.
