Bivariate transformation
WebIn the context of the EU GRACIOUS project, we propose a novel procedure for similarity assessment and grouping of nanomaterials. This methodology is based on the (1) Arsinh transformation function for scalar properties, (2) full curve shape comparison by application of a modified Kolmogorov-Smirnov metric for bivariate properties, (3) Ordered Weighted … WebThe polar method is based on the polar coordinate transformation X = R cos Θ, Y = R sin Θ, where Θ ∼ U ( 0, 2 π) and R ∼ f R are independent. Using standard transformation rules it follows that the joint pdf of X and Y satisfies: f X, …
