Geological Modeling Method Based on the Normal Dynamic Estimation of Sparse Point Clouds
Mathematics, 2021 The effect of geological modeling largely depends on the normal estimation results of geological sampling points. However, due to the sparse and uneven characteristics of geological sampling points, the results of normal estimation have great uncertainty.

Bootstrap BCa confidence intervals for a standardized mean difference in a paired samples design using a pooled standard deviation [PDF]
Tutorials in Quantitative Methods for PsychologyA standardized mean difference in a paired samples design using a pooled standard deviation, dp, requires knowledge of the population correlation, rho, in order to generate an accurate estimate of a noncentral t confidence interval (CI).
