The test statistic = signal/noise = 28.4/11.7 = 2.43 captures the evidence for treatment differences. Larger values, either positive or negative, are an indication of treatment differences.

Calculate the upper and lower control limits (UCL and LCL) these are the statistical signals that will show when the process is not running in its usual mode. 

The correlation function corresponds to the memory function, which indicates to which degree values of one function at time t are comparable to values of another function at time t — a before. For statistical signals, the similarity usually decreases rapidly with increasing shift a. For white noise, all values are independent of the others, and the auto-correlation function is proportional to a delta function. The proportionality factor is the second moment (12 of the noise signal.

Indicators of disproportionality are measures of association and even quite extreme results may not be causal. The next step is clinical review of the relevant cases and to assess any other relevant information which may be available (see later). Many practitioners do not regard mathematical disproportionahty alone as sufficient to raise a signal. Thus, use of the terms statistical signal and signal of disproportionate reporting is emerging. 

Systematic use of data mining tools in a large spontaneous ADR database will identify large numbers of statistical signals. Evaluating all of them in detail would have major resource implications but many will turn out not to be real or to require no action. Possible signals have often been evaluated or dismissed on the basis of subjective judgements but two methods of prioritisation have been proposed ...
