Loss Triangle as described by HB Actuarial Services, Inc. Complex Calculations Made Easy to Understand. A loss triangle is the primary method in which actuaries organize claim data that will be used in an actuarial analysis. The reason it is called a loss triangle is that a typical submission of claim data from a client company shows numeric values forming a triangle when viewed. The easiest loss triangle to explain is the accident year paid loss triangle. This loss triangle totals paid loss data in each of two categories. The first is accident year. Simply put, all paid losses from all claims occurring in the accident year are totaled.
where RL (dB) is the return loss in dB, P i is the incident power and P r is the reflected power. Return loss is related to both standing wave ratio (SWR) and reflection coefficient (Î³). Increasing return loss corresponds to lower SWR.Return loss is a measure of how well devices or lines are matched.A match is good if the return loss is high. A high return loss is desirable and results in a lower insertion loss.eturn loss is the negative of the magnitude of the reflection coefficient in dB. Since power is proportional to the square of the voltage, return loss is given by, where the vertical bars indicate magnitude.
