The relative operating characteristic (ROC) is a popular statistical method to measure the association between observed and diagnosed presence of a characteristic. The diagnosis of presence or absence depends on whether the value of an index variable is above a threshold. ROC considers multiple possible thresholds. Each threshold generates a two-by-two contingency table, which contains four central entries: hits, misses, false alarms, and correct rejections. ROC reveals for each threshold only… 
Recommendations for using the relative operating characteristic (ROC)
The relative operating characteristic (ROC) is a widely-used method to measure diagnostic signals including predictions of land changes, species distributions, and ecological niches. The ROC measures
The Total Operating Characteristic from Stratified Random Sampling with an Application to Flood Mapping
This manuscript derives a new methodology that uses stratified random sampling to generate the TOC and shows visually and quantitatively each index’s diagnostic ability relative to baselines.
Positive and negative predictive values by the TOC curve
Sensitivity and specificity are popular measures described by the receiver operating characteristic (ROC) curve. There are also two other measures such as the positive predictive value (PPV) and
The MCC-F1 curve: a performance evaluation technique for binary classification
The MCC-F1 curve is proposed, which combines two informative single-threshold metrics, MCC and the F1 score, and provides a single value that integrates many aspects of classifier performance across the whole range of classification thresholds.
Techniques for the Validation of LUCC Modeling Outputs
This chapter distinguishes between purely quantitative validation techniques and those that also consider the spatial allocation of simulated land use/cover changes (LUCC), and compares a group of the most common model software programs, in order to list their validation capabilities.
Abstract. The importance of spatial accuracy of land use/cover change maps necessitates the use of high performance models. To reach this goal, calibrating machine learning (ML) approaches to model
Landscape Applications of Machine Learning: Comparing Random Forests and Logistic Regression in Multi-Scale Optimized Predictive Modeling of American Marten Occurrence in Northern Idaho, USA
The American marten is a species that is dependent on old conifer forest at middle to high elevations and is highly sensitive to habitat loss and fragmentation. Our goal was to compoare logistic
A Comparative Study of Machine Learning Techniques to Simulate Land Use Changes
This paper applies and compares three widely used data mining models: classification and regression tree (CART), multivariate adaptive regression spline (MARS) and random forest (RF), to simulate urban LUCs of Shirgah in Iran and verifies that having the highest accuracy in the testing run does not necessarily guarantee the highest accuracies in the validating run.
Comparing Quantity, Allocation and Configuration Accuracy of Multiple Land Change Models
Compared the quantity, allocation, and configuration accuracy of four inductive pattern-based spatial allocation land change models (SLEUTH, GEOMOD, Land Change Modeler (LCM), and FUTURES), which suggest some models may better simulate quantity and allocation at the trade-off of configuration accuracy, and vice versa.

A Simple Generalisation of the Area Under the ROC Curve for Multiple Class Classification Problems
This work extends the definition of the area under the ROC curve to the case of more than two classes by averaging pairwise comparisons and proposes an alternative definition of proportion correct based on pairwise comparison of classes for a simple artificial case.

The Relative Operating Characteristic in Psychology
The ROC is an analytical technique that quite effectively isolates the effects of the observer's response bias, or decision criterion, in the study of discrimination behavior and enhances the understanding of the perceptual and cognitive phenomena that depend directly on these fundamental processes.

Thirteen recommendations are made to enable the objective selection of an error assessment technique for ecological presence/absence models and a new approach to estimating prediction error, which is based on the spatial characteristics of the errors, is proposed.
