  2. Sankey diagram - Wikipedia

    en.wikipedia.org/wiki/Sankey_diagram

    Sankey diagrams can also visualize the energy accounts, material flow accounts on a regional or national level, and cost breakdowns. [2] The diagrams are often used in the visualization of material flow analysis. Sankey diagrams emphasize the major transfers or flows within a system. They help locate the most important contributions to a flow.

  4. Symbolic regression - Wikipedia

    en.wikipedia.org/wiki/Symbolic_regression

    Further methods such as Exact Learning attempt to transform the fitting problem into a moments problem in a natural function space, usually built around generalizations of the Meijer-G function. [5] By not requiring a priori specification of a model, symbolic regression isn't affected by human bias, or unknown gaps in domain knowledge. It ...

    Sankey's diagram, 1898. In an 1898 article about the energy efficiency of a steam engine in the Minutes of Proceedings of the Institution of Civil Engineers Sankey introduced the first energy flow diagram: a visualisation to be christened Sankey diagram. [4] Sankey gave the following explanation how to read the image:

    The following MATLAB code will plot the root locus of the closed-loop transfer function as varies using the described manual method as well as the rlocus built-in function: % Manual method K_array = ( 0 : 0.1 : 220 ). ' ; % .' is a transpose.

  8. Newey–West estimator - Wikipedia

    en.wikipedia.org/wiki/Newey–West_estimator

    In Stata, the command newey produces Newey–West standard errors for coefficients estimated by OLS regression. [13] In MATLAB, the command hac in the Econometrics toolbox produces the Newey–West estimator (among others). [14] In Python, the statsmodels [15] module includes functions for the covariance matrix using Newey–West.

  9. Heteroskedasticity-consistent standard errors - Wikipedia

    en.wikipedia.org/wiki/Heteroskedasticity...

    Heteroskedasticity-consistent standard errors that differ from classical standard errors may indicate model misspecification. Substituting heteroskedasticity-consistent standard errors does not resolve this misspecification, which may lead to bias in the coefficients. In most situations, the problem should be found and fixed. [5]
