Moment in statistics formula

WebIf the curve of a distribution is more outlier prone (or heavier-tailed) than a normal or mesokurtic curve then it is referred to as a Leptokurtic curve. If a curve is less outlier prone (or lighter-tailed) than a normal curve, it is called as a platykurtic curve. Kurtosis is measured by moments and is given by the following formula −. WebMoments are vectors, so they have magnitude and direction and obey all rules of vector addition and subtraction described in Chapter 2.Additionally, moments have a center of rotation, although it is more accurate to say that they have an axis of rotation.In two dimensions, the axis of rotation is perpendicular to the plane of the page and so will …
