MANOVA with Summary Statistics: A STATA Program

A Statistics Program at NCAR, Project Summary

A grand scientific challenge for this century is to understand the complex interrelationships among the atmosphere, ocean, land processes, biosphere and human activities that define the Earth System. Coupled with this effort is the need to predict changes to our environment and to translate such changes into more immediate economic and societal impacts. There is a corresponding challenge for st...

A Monte Carlo Comparison of Robust MANOVA Test Statistics

Multivariate Analysis of Variance (MANOVA) is a popular statistical tool in the social sciences, allowing for the comparison of mean vectors across groups. MANOVA rests on three primary assumptions regarding the population: (a) multivariate normality, (b) equality of group population covariance matrices and (c) independence of errors. When these assumptions are violated, MANOVA does not perform...

Summary statistics in vision

Non parametric ROC summary statistics

Receiver operating characteristic (ROC) curves are useful statistical tools for medical diagnostic testing. It has been proved its capability to assess diagnostic marker’s ability to distinguish between healthy and diseased subjects and to compare different diagnostic markers. In this paper we introduce non parametric ROC summary statistics to assess a ROC curve across the entire range of FPFs ...

Visualizing Summary Statistics and Uncertainty

The graphical depiction of uncertainty information is emerging as a problem of great importance. Scientific data sets are not considered complete without indications of error, accuracy, or levels of confidence. The visual portrayal of this information is a challenging task. This work takes inspiration from graphical data analysis to create visual representations that show not only the data valu...
