valuestudentTTest

:: Vector v Double
=> PositionTest
one- or two-tailed test
-> v Double
Sample A
-> v Double
Sample B
-> Maybe (Test StudentT)

Two-sample Student's t-test. It assumes that both samples are normally distributed and have same variance. Returns Nothing if sample sizes are not sufficient.

valuewelchTTest

:: Vector v Double
=> PositionTest
one- or two-tailed test
-> v Double
Sample A
-> v Double
Sample B
-> Maybe (Test StudentT)

Two-sample Welch's t-test. It assumes that both samples are normally distributed but doesn't assume that they have same variance. Returns Nothing if sample sizes are not sufficient.

valuepairedTTest

:: Vector v (Double, Double)
=> PositionTest
one- or two-tailed test
-> v (Double, Double)
paired samples
-> Maybe (Test StudentT)

Paired two-sample t-test. Two samples are paired in a within-subject design. Returns Nothing if sample size is not sufficient.
