A baseline normalization was applied for the absolute values of the event-related fields, including the time range of −300 to 0 ms as baseline window.
The pool of the replicate arrays, CM-00h-1 and CM-00h-2, was used as a baseline for normalization and was applied to the calculation of log2 ratios, M, for the test arrays.
As in prior studies, the "difference signal" as a percent change from baseline on a trial by trial basis was computed by the baseline normalization analysis, followed by a trial rejection procedure [5], [14], [15].
Eligible patients had responded to somatostatin analogues, defined as a reduction in GH of 50% or more from baseline, normalization of IGF-1 or a reduction of 30% or more, after a minimum period of 2 months of treatment.
The results of ChIPDiff were used as a baseline to gauge the performance of each different normalization method.
Mulitvariate pattern analysis was performed via linear discriminant analysis (LDA), using at each individual time point the firing rates of all neurons in EC or hippocampus as features (after averaging across a sliding 500 ms window and z-scoring across trials instead of baseline normalization).
After normalization and baseline transformation performed using median of UU samples as a baseline; we decided to focus on those genes that reliably change their expression, then we filtered the microarrays following three conditions: 1) Filter by value.
"Often the qualification is used as a baseline," Hack says.
The calculations use 1990 as a baseline.
These weeks would function as a baseline.
The average global temperature from 1950-1981 as a baseline.
