#Coherence x series
In the FD, the input is a continuous multivariate data matrix $X=$, where each column is a series (e.g., a time-series). The following notation will be used: symbol This leads to refinement of X-Matrix, more coherence and stronger alignment.FourierAnalysis estimates coherence both in the frequency domain, in this unit, and in the time-frequency domain, in unit timefrequencybi.jl. Its visualising and discussing these correlations that is often where the magic happens, as it exposes differences in understandings and perspectives on what all the pieces mean and how relate to each other. Or whether Evidence 4 is relevant given its relatively poor correlations with both Tactics and Aspiration. Or whether Tactic 2 is the best investment given its relatively poor correlations with both Strategies and Evidence. For example we might question why Strategy 3 only has Tactic 2 with an indirect/weak correlation. Remember, this is just a hypothesis, and by looking at the patterns of correlations around the X-Matrix we can see and discuss the overall coherence. Similarly, Strategy 1 has a direct/strong correlation with Aspiration 2, but Strategy 2 has no correlation, and Strategy 3 only has indirect/weak correlation. As do all the Strategies, which indicates high coherence. In other words this suggests that Strategy 1 contributes directly or strongly to Aspiration 1.

Here we can see that there is a direct or strong correlation between “Increase Revenue +10%” (Aspiration 1) and “Global Domination” (Strategy 1). (If using likelihood, a third variant would be needed, such as a circle with a dot in the middle). Filled circles represent direct or strong correlations, while empty circles represent indirect or weak correlations. I have tried letters and colours, and have recently settled on filled and empty circles, as in the example below. Having decided on an approach, a symbol is used in each cell to visualise the nature of each correlation. An X-Matrix where everything correlates with everything is usually too convenient and can be a sign of post-hoc justification. Whatever the language, there is always the option of none. This adds a third option, and therefore another level of complexity, but the language can be useful.
#Coherence x how to
I promised to say more about correlations in my last post on how to TASTE Success with the X-Matrix .
