Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Nonlinearity and Inflation Rate Differential Persistence: Evidence from the Eurozone. [PDF]

We employ a linear unit root test as well as a nonlinear two-regime Threshold Autoregressive (TAR) unit root test to determine whether inflation differentials in the Eurozone during the period 1970-2009 were persistent or transitory.

Exploring the Achievement Gap Between White And Minority Students in Texas

Education Policy Analysis Archives, 2003
The Texas Assessment of Academic Skills (TAAS) has been used to document and track an achievement gap between white and minority students in Texas.  Some educators have credited the TAAS with fueling a drive to close the achievement gap while others ...

Confidence interval and test for the mean of a zero-inflated two-parameter negative binomial distribution

Research in Statistics
Zero-inflated over-dispersed count data arise in many applications, motivating the zero-inflated negative binomial family. We develop likelihood-based inference for the negative binomial two-parameter (NB2) component mean [Formula: see text] under a zero-
