		The convergence formula defines a gradual transition from the current distribution of emissions, to an equal per-capita distribution in the "convergence year".

		The exponential formula allows a smoother transition, although the penalty for higher emissions in earlier years, is a more rapid drop later.

		Further, these curves look quite a bit like the graph of an exponential function, but from what we see, it might just as well be part of a parabola or of one of a number of other curves that result when various algebraic forms are graphed.
		In this situation, the logarithmic function can be used to rewrite the exponential growth formula into a form that will allow us to create a plot that does give a straight line when data is the result of an exponential growth (or decay) process.
		If the original exponential growth formula is correct and we plot ln N along the vertical axis of the graph (rather than N itself), and t along the horizontal axis, then the equation of the plot we are preparing will have the generic form

		The formula for correlation coefficient is available in virtually all spreadsheets and most charting packages, and it's in any statistics text.
		The correlation for the exponential model (logarithmic prices) is greater than for the linear model, which shows that the exponential model is a better fit for the data given.
		In pure statistical analysis, the significance of correlation is determined by another complicated formula, which is usually listed in tables of values in the appendix of statistics texts.

		Such improvements include the exponential moving average (ema) from last week, the weighted moving average (wma), and the Welles Wilder moving average (wwma).
		It is no surprise then that he has developed a moving average formula of his own which is most similar mathematically to the exponential formula.
		In this case you can see that the 30 period wwma is very slow to respond because the current price is only 1/30th of the total value whereas in the short (5 period) wwma, it is given 1/5th of the weight.
