A single-case statistical analysis in which the most conservative contrast (i.e., hardest to reject) based on baseline data, is projected as a line through the adjacent/treatment phase. A binomial statistical test is then conducted to determine if proportion of treatment data above the comparison line is statistically significant. A 0.25 standard deviation in the direction of the predicted treatment effect is added to the baseline line to reduce problems associated with autocorrelation.
