Analysts hypothesized that algorithms may have responded to Monday's trades falling below the market's 50-day moving average or as measures of market volatility grew.
In addition, some recent studies have suggested that distributed lag models (DLMs) that allow differential PM mortality effects spread over multiple days may be preferable to single-day or multiple-day moving average PM exposure measures (Schwartz 2000; Smith et al. 2000).
The result is a more accurate estimate of learning-related changes in choice behavior than arises from standard moving average or choice-point measures of learning [56].
From these daily data we calculated the 7-day moving average for each measure.
Lines showing the moving average of the measured LD and the predicted LD curve from fitting the Sved [ 9] equation followed each other well, indicating that the population behaved as predicted with respect to decline of LD over distance.
The four-week moving average, a less volatile measure of initial claims, held at 426,250.
The four-week moving average, a less volatile measure, dropped for a third week, to 436,000.
The four-week moving average for claims, a measure intended to smooth out weekly fluctuations, rose by 5,750, to 388,250.
The four-week moving average, considered a better measure of labor market trends, also fell to 370,000, dropping by 5,500.
The four-week moving average, a less-volatile measure, declined to 359,000 from 366,000, also the lowest since March 2008.
