Carlin Trend

The Carlin Trend is a statistical method used in quality control to monitor data over time, especially for detecting small but persistent shifts in a process. It involves plotting the most recent data points against older ones to identify if there's a consistent upward or downward trend, indicating potential issues. By focusing on the recent data compared to the historical baseline, it helps detect gradual changes sooner than traditional methods, enabling timely corrective actions. This technique is particularly useful in industries where maintaining consistent product quality is critical.
