• Abstract: In this study, we present a method for predicting the representativity of the phase fraction observed in a single image (2D or 3D) of a material. Traditional approaches often require large datasets and extensive statistical analysis to estimate the Integral Range, a key factor in determining the variance of microstructural properties. Our method leverages the Two-Point Correlation function to directly estimate the variance from a single image (2D or 3D), thereby enabling phase fraction prediction with associated confidence levels. We validate our approach using open-source datasets, demonstrating its efficacy across diverse microstructures. This technique significantly reduces the data requirements for representativity analysis, providing a practical tool for material scientists and engineers working with limited microstructural data. To make the method easily accessible, we have created a web-application, \url{www.imagerep.io}, for quick, simple and informative use of the method.

  We develop a Bayesian platform for binary and ordinal item MIRT which requires minimal tuning and scales well on large datasets. We address the seemingly insurmountable problem of unknown latent factor dimensionality with tools from Bayesian nonparametrics. Our method reliably recovers both the factor dimensionality as well as the latent structure on high-dimensional synthetic data even for small samples.
