What does Platykurtic distribution indicate?

What does Platykurtic distribution indicate?

What Does Platykurtic Mean? The term “platykurtic” refers to a statistical distribution in which the excess kurtosis value is negative. For this reason, a platykurtic distribution will have thinner tails than a normal distribution will, resulting in fewer extreme positive or negative events.

What does a Platykurtic distribution look like?

Platykurtic distributions have negative kurtosis values. A platykurtic distribution is flatter (less peaked) when compared with the normal distribution, with fewer values in its shorter (i.e. lighter and thinner) tails.

When the shape of the distribution is Platykurtic the value will be?

Statistically, if the value for the kurtosis of your distribution is less than 3 or less than zero for a standard normal distribution then your distribution can be classified as platykurtic.

What is Platykurtosis?

Noun. platykurtosis (uncountable) (statistics) The property of having kurtosis less than that of a normal distribution; equivalently, having negative excess kurtosis.

What is Leptokurtic curve?

What Is Leptokurtic? Leptokurtic distributions are statistical distributions with kurtosis greater than three. It can be described as having a wider or flatter shape with fatter tails resulting in a greater chance of extreme positive or negative events. It is one of three major categories found in kurtosis analysis.

How do you determine Leptokurtic?

A leptokurtic distribution has excess positive kurtosis, where the kurtosis is greater than 3. The tails are fatter than the normal distribution.

What is the value of b2 if the curve is Platykurtic?

Mesokurtic Curve – Value of β2 is equal to 3. Platykurtic Curve – Value of β2 is less than 3.

What is the difference between Platykurtic and Leptokurtic?

In statistics|lang=en terms the difference between platykurtic and leptokurtic. is that platykurtic is (statistics) said of a distribution if it has negative kurtosis while leptokurtic is (statistics) said of a distribution if it has positive kurtosis.

Is T distribution a Platykurtic?

The T distribution is an example of a leptokurtic distribution. It has fatter tails than the normal (you can also look at the first image above to see the fatter tails). Therefore, the critical values in a Student’s t-test will be larger than the critical values from a z-test.

What is Mesokurtic distribution?

What Is a Mesokurtic Distribution? Mesokurtic is a statistical term used to describe the outlier characteristic of a probability distribution in which extreme events (or data that are rare) is close to zero. A mesokurtic distribution has a similar extreme value character as a normal distribution.

How do you read Leptokurtic?

If the kurtosis is less than zero, then the distribution is light tails and is called a platykurtic distribution. If the kurtosis is greater than zero, then the distribution has heavier tails and is called a leptokurtic distribution. The problem with both skewness and kurtosis is the impact of sample size.

How do I know if my data is Leptokurtic or Platykurtic?

K < 3 indicates a platykurtic distribution (flatter than a normal distribution with shorter tails). K > 3 indicates a leptokurtic distribution (more peaked than a normal distribution with longer tails). K = 3 indicates a normal “bellshaped” distribution (mesokurtic). K < 3 indicates a platykurtic distribution.
