The controversy surrounding the validity of these studies, regarding the failure to compare data obtained in different laboratories, was partly ascribed to differences in the experimental design.
This is unfortunately typical of what happens when comparing different results in text classification: There are often differences in the experimental setup or the evaluation that complicate the interpretation of the results.
In reality, however, the target signals will differ from the dictionary signals owing to the differences in the experimental conditions under which they are collected.
The authors' efforts paid off in the end, indicating that micro differences in the experimental design can have quite different outcome.
In addition to differences in the experimental design, the analysis reported here differs from other reports.
Differences in the experimental conditions employed may partly explain the differing results obtained.
This data set is an interesting test case for CTen because the differences in the experimental protocol tests CTen's performance when using different microarray technologies and biological conditions.
Due to differences in the experimental set-up across rearing temperatures (see above), three different analyses were run for chill-coma recovery time and longevity.
The discrepancies could derive from the differences in the experimental dietary fat levels, feeding durations, and cell types studied.
Statistical analysis indicated that there were significant differences in the experimental group's academic scores.
Instead, these inconsistencies may reflect differences in the experimental design of each study.
