It can be used on small sample sizes with reliable results, and it can effectively differentiate between usable and unusable systems.
We consider successively k = 1, 3, 5, which are all usual choices when the method is used on small sample data.
Capillary pressure by mercury injection up to 30,000 psi was performed on small samples using 'Micromeriticsʼ apparatus, where a clean and dry sample is loaded into a glass penetrometer consisting of a sample chamber attached to a cylindrical coaxial capacitor capillary stem.
This method not only reduces the dimension of the feature vector, making it more compact, but also can be used even on small-sample-size cases[18].
Although earlier reports had suggested no increase in fighting in girls with CAH [ 43, 44], these reports were based on small samples and used weak measures (e.g., unspecified or single interview questions).
This formula was used to account for mean scores based on small samples as these numbers could potentially over or underestimate the value of a resource.
The case control studies used in our meta-analysis were based on small samples and were of lower scientific evidence level, which might have decreased our ability to detect a difference in the distribution of HLA-DRB1.
However, those studies often relied on small samples (<20) and seldom used a no-treatment patient control condition.
A few studies have analyzed a limited set of BE characteristics using GIS techniques [ 33], or have focused on small samples from a narrow study area [ 34].
Although some researchers suggest that structural equation modelling (SEM) and confirmatory factor analysis (CFA) should not be used on samples smaller than 200, others suggest minimum sample sizes between 100 and 200 (3200
