We develop and apply a set of hypothesis tests with which to study changes in the angular distribution of points in delay space. Crack and Ledoit (1996) plotted daily stock returns against themselves with one day's lag. (This might be described as a plot in delay space). The graph shows these...

Several studies have shown the existence of significant differences in the rate of new business creation between men and women. Specifically, it has been shown that women are much less likely to be involved in entrepreneurship than men worldwide. It is not yet understood, however, if such...

We develop and apply a set of hypothesis tests with which to study changes in the angular distribution of points in delay space. Crack and Ledoit (1996) plotted daily stock returns against themselves with one day's lag. The graph shows these points collected along several rays from the origin....
