👉 In econometrics, a "betrend" is an indicator that a series of prices or values are trending in a specific direction. It's like a trend line on a graph where the slope changes from positive to negative over time. This can be useful for understanding if there's a change in price and how it's changing. Example: A company's stock price has been trending up consistently, but recently it's started declining. The betrend might show that this trend is now moving down.
