VTESTNORM function

Description

VTESTNORM(normalitytest,variable[,filter]) returns the P-value of a test for normal distribution on a variable. An optional filter can be specified.

Normalitytest may be

• KOLSMIR for the Kolmogorov-Smirnov test
• SHAPWILK for the Shapiro-Wilk test
• SHAPFRANC for Shapiro-Francia test
• DAGPEAR for the D'Agostino-Pearson test

See Tests for normal distribution for details.

Example

VTESTNORM(SHAPWILK,bmi) returns the P-value for the Shapiro-Wilk test on the variable bmi.

Note

This function calculates a statistic on a variable. Be careful when you use this function in cells of the columns that correspond to the variable, because this actually adds a value to the variable which can lead to unexpected and faulty results. You can exclude the cell to avoid this.
