Comparing two small samples with an unstable, treatment-independent baseline

S Janušonis - Journal of neuroscience methods, 2009 - Elsevier
Due to time and resource constraints, small samples (N=3–7 cases per group) are often
used in neurobiological studies that employ multiple techniques. In a simulation study, five …

[HTML][HTML] Predicting the distribution of serotonergic axons: a supercomputing simulation of reflected fractional Brownian motion in a 3D-mouse brain model
