Interest has been growing in testing for nonlinearity or chaos in economic data, but much controversy has arisen about …-blind controlled competition among five highly regarded tests for nonlinearity or chaos with ten simulated data series. The data … for nonlinearity or noisy chaos. …

misspecification of the conditional mean may lead to spurious rejections of the null hypothesis of no ARCH. Nonlinearity is a prime … example of this phenomenon. There is little work on the extent of the effect of neglected nonlinearity on the properties of … neglected nonlinearity. Monte Carlo evidence shows that the problem is serious and that the new methods alleviate this problem …
