The phrase "a technical correlation between" is correct and usable in written English.
It can be used when discussing the relationship or connection between two technical subjects or variables.
Example: "The study aims to establish a technical correlation between software performance and user satisfaction."
Alternatives: "a technical relationship between" or "a technical link between".
Technical correlation of gene expression was examined between the Affymetrix and Nanostring platforms by calculating Pearson's correlation coefficient (r) across all 50 genes for fold change estimates obtained using the same RNA samples.
Because our macroarray quality test showed a high correlation between technical replicates, two biological replicates per each time point were examined.
In terms of the reproducibility of the method for collecting 5′-end reads, we found a high correlation between technical replicates and validated the method using quantitative real-time PCR in our previous paper [ 32].
Our analysis shows a correlation between technical validation and follow-on funding.
As it may be difficult to establish publication bias by visual inspection [ 20], we used the Mann-Whitney U test and Spearman's rank correlation test to determine a correlation between technical and clinical success rates per stent type and the number of patients.
This was used to fit a linear model to the expression data for each probe taking into account the inter-technical replicate correlation between each microarray hybridisation.
We found a very high correlation between technical replicates and a good correlation between different batches.
A Pearson correlation calculation of expression values from the five technical replicates showed a good correlation between microarray and TLDA expression levels (average correlation coefficient = 0,7; see additional file 1).
This trend was not due to a technical artifact since no correlation between glycoprofile and concentration of PrPres existed.
