Web25 de fev. de 2016 · $\begingroup$ I'm looking at a social science theory that predicts that the distribution of certain variables should be leptokurtic. Some of the literature will test statistically whether the observed kurtosis is different than normal. The theory also predicts that these distributions should become more leptokurtic under certain conditions. … Web7 de mar. de 2024 · Kurtosis is a statistical measure which defines how the tails of your data distribution differ from the tails of a normal distribution. High kurtosis indicates you …
WebThe source signals are independent of each other. The values in each source signal have non-Gaussian distributions. Independence: As per assumption 1, the source signals are independent; however, their signal mixtures are not. This is because the signal mixtures share the same source signals.
