软件的帮助里面应该有的。

还是问问马尔文的工程师吧！

其实是一些常见函数，可以参考仪器的帮助文件。自定义函数：

偏态？Skew：
Syntax : Skew(pType)

Group : Stats.

Description : Returns the Skew of the current result distribution based on a distribution type (pType).



As an alternative the distribution type can be used directly, in the form rtDistribution type.

The values of pType and distribution type variables are:

0 = Volume or rtVolume
1 = Surface or rtSurface
2 = Length or rtLength
3 = Number or rtNumber

See Distribution statistics for more information on skew.

Example
Calculations to determine the volume skew



Private Function Calc() As Variant
volskew= Stats.Skew(0)
'Round returns the calculated value to 3 decimal places
Calc =Round (volskew ,3)
End Function

Or

Private Function Calc() As Variant
volskew = Stats.Skew(rtVolume)
'Round returns the calculated value to 3 decimal places
Calc =Round (volskew ,3)
End Function



Return to Result statistics list

峰态？Kurtosis
Syntax : Kurtosis(pType)

Group : Stats.

Description : Returns the Kurtosis of the current result distribution based on a distribution type (pType).



As an alternative the distribution type can be used directly, in the form rtDistribution type.

The values of pType and distribution type variables are:

0 = Volume or rtVolume
1 = Surface or rtSurface
2 = Length or rtLength
3 = Number or rtNumber

See Distribution statistics for more information on kurtosis.

Examples
Calculations to determine the volume kurtosis

Private Function Calc() As Variant
volkurt = Stats.Kurtosis(0)
Round returns the calculated value to 3 decimal places
Calc =Round (volkurt ,3)
End Function

Or

Private Function Calc() As Variant
volkurt = Stats.Kurtosis(rtVolume)
'Round returns the calculated value to 3 decimal places
Calc =Round (volkurt ,3)
End Function
