The phrase "actual association study" is correct and usable in written English.
It can be used in contexts related to research, particularly in fields like genetics or epidemiology, where studies investigate the relationships between variables.
Example: "The researchers conducted an actual association study to determine the link between the genetic markers and the disease."
Alternatives: "real association study" or "genuine association study".
For this reason, in an actual association study, sampling variation would be considered and could be estimated parametrically by including in the design sub-pools of independent samples of cases and controls.
However, in an actual association study, pooled DNA estimates are not compared within and between pools of the same individuals but rather between different pools consisting of different individuals.
In an actual association study, sampling variation is added to the parameters considered in the present study which focused on technical replicates within and between DNA pools of the same group of individuals and compared allele frequency estimates for pooled DNA from this group of individuals to individual genotyping.
Therefore, a challenging yet important first step of any association study will ideally be to identify the actual structural forms of the mCNV of interest.
The actual association between stimuli difference and classification results is a subject worthy of systematic investigation in a dedicated study, which we propose to conduct in future work.
However, because the variation in serum marine n-3 FAs occurs randomly, the actual association of marine n-3 FAs with fibrinogen is likely to be stronger than was observed in the current study.
Some studies naturally provided more information on one or the other, rather than measure a perceived or actual association between the two.
Genome wide association study.
Design: Case control association study.
It's called a genome-wide association study, or GWAS.
Accordingly, it is possible that the actual association between BMI and food detection bias would be u-shaped when the full range of BMI scores is considered: within the typical BMI range the association seems to be negative (c.f. this study), but after a certain threshold value of BMI the association would be rendered positive.
