Syntax of ANOVAF(), ANOVAP() and TTEST()
These functions are supported in the Fx Tile in Magic.
Does anyone have some syntax examples ? The function requires an aggregation context suggesting a group by action

Function Name
Description
Example
ANOVAF
Returns the F-value of a one-way Analysis of Variance of the samples. At least two samples must be provided, and each sample must have at least two non-null values. Note that a one-way ANOVA on two samples is equivalent to the Student's t-test (see the TTEST function).
See also: ANOVAP()
ANOVAF(sample1,sample2[,sample3[,...,sampleN]])
ANOVAP
Returns the p-value of a one-way Analysis of Variance of the samples. At least two samples must be provided, and each sample must have at least two non-null values. Note that a one-way ANOVA on two samples is equivalent to the Student's t-test (see the TTEST function).
See also: ANOVAF()
ANOVAP(sample1,sample2[,sample3[,...,sampleN]])
TTEST
Returns the p-value result of a Student's t-test. Arguments sample1 and sample2 are two numeric columns with at least 2 non-null values each. The tails argument is either 1 or 2, indicating a one- or two-tailed test. The type argument is a number 1 through 3. Type 1 is a paired sample test; for this type of test, values in both sample1 and sample2 must be non-null or be ignored. Type 2 is for two samples with the assumption of equal variance. Type 3 is for two samples without the assumption of equal variance.
TTEST(sample1,sample2,tails,type)

Update: I figured it out.. looks like in magic , the function needs to be added within the Group by tile add formula providing at least 2 fields containing the samples to analyze
