Normality function

Check normality

Check normality through Shapiro-Wilks test

Normality(x, p=0.05)

Arguments

• x: numerical vector
• p: level of significance

Details

Normality via Shapiro-Wilks test. Kolmogorov-Smirnov is apparently too weak for small samples. The word of caution: this function only helps to decide if the data complains with parametric methods ("normal").

Returns

Character vector of length one.
