This article evaluates the reliability of sensitivity tests (Leamer 1978). Using Monte Carlo methods we show that, first, the definition of robustness exerts a large influence on the robustness of var¬iables. Second and more importantly, our results also demonstrate that inferences based on sen¬sitivity tests are most likely to be valid if determinants and confounders are almost uncorrelated and if the variables included in the true model exert a strong influence on outcomes. Third, no definition of robustness reliably avoids both false positives and false negatives. We find that for a wide variety of data-generating processes, rarely used definitions of robustness perform better than the frequently used model averaging rule suggested by Sala-i-Martin. Fourth, our results also suggest that Leamer’s extreme bounds analysis and Bayesian model averaging are extremely un¬likely to generate false positives. Thus, if based on these inferential criteria a variable is robust, it is almost certain to belong into the empirical model. Fifth and finally, we also show that research¬ers should avoid drawing inferences based on lack of robustness.

ABSTRACT Measures of the apparent electrical conductivity (ECa) of soil are used in many studies as indicators of spatial variability in physicochemical characteristics of production fields. Based on these measures, management zones (MZs) are delineated to improve agricultural management. However, these measures include outliers. The presence or incorrect identification and exclusion of outliers affect the variogram function and result in unreliable parameter estimates. Thus, the aim of this study was to model ECa data with outliers using methods based on robust approximation theory and model-based geostatistics to delineate MZs. Robust estimators developed by Cressie-Hawkins, Genton and MAD Dowd were tested. The Cressie-Hawkins semivariance estimator was selected, followed by the semivariogram cubic fit using Akaike information criterion (AIC). The robust kriging with an external drift plug-in was applied to fitted estimates, and the fuzzy k-means classifier was applied to the resulting ECa kriging map. Models with multiple MZs were evaluated using fuzzy k-means, and a map with two MZs was selected based on the fuzzy performance index (FPI), modified partition entropy (MPE) and Fukuyama-Sugeno and Xie-Beni indices. The defined MZs were validated based on differences between the ECa means using mixed linear models. The independent errors model was chosen for validation based on its AIC value. Thus, the results demonstrate that it is possible to delineate an MZ map without outlier exclusion, evidencing the efficacy of this methodology.

Analyses of population genetic structure has become a standard approach in population genetics. In polyploid complexes, clustering analyses can elucidate the origin of polyploid populations and patterns of admixture between different cytotypes. However, combining diploid and polyploid data can theoretically lead to biased inference with (artefactual) clustering by ploidy. We used simulated mixed-ploidy (diploid-autotetraploid) data to systematically compare the performance of k-means clustering and the model-based clustering methods implemented in STRUCTURE, ADMIXTURE, FASTSTRUCTURE and INSTRUCT under different scenarios of differentiation and with different marker types. Under scenarios of strong population differentiation, the tested applications performed equally well. However, when population differentiation was weak, STRUCTURE was the only method that allowed unbiased inference with markers with limited genotypic information (co-dominant markers with unknown do sage or dominant markers). Still, since STRUCTURE was comparably slow the much faster but less powerful FASTSTRUCTURE provides a reasonable alternative for large datasets. Finally, although bias makes k-means clustering unsuitable for markers with incomplete genotype information, given large numbers of loci (>1000) with known dosage k-means clustering was superior to FASTSTRUCTURE in terms of power and speed. We conclude that STRUCTURE is the most robust method for the analysis of genetic structure in mixed-ploidy populations, although alternative methods should be considered under some specific conditions.

Paper Abstract

To develop a good software estimation model fitted to actual data, the evaluation criteria of goodness of fit is necessary. The first major problem discussed here is that ordinary relative error used for this criterion is not suitable because it has a bound in the case of under-estimation and no bound in the case of overestimation. We propose use of a new relative error called balanced relative error as the basis for the criterion and introduce seven evaluation criteria for software estimation models. The second major problem is that the ordinary least-squares method used for calculation of parameter values of a software estimation model is neither consistent with the criteria nor robust enough, which means that the solution is easily distorted by outliers. We propose a new consistent and robust method called the least-squares of inverted balanced relative errors (LIRS) and demonstrates its superiority to the ordinary least-squares method by use of five actual data sets. Through the analysis of these five data sets with LIRS, we show the importance of consistent data collection and development standarization to develop a good software sizing model. We compare goodness of fit between the sizing model based on the number of screens, forms, and files, and the sizing model based on the number of data elements for each of them. Based on this comparison, the validity of the number of data elements as independent variables for a sizing model is examined. Moreover, the validity of increasing the number of independent variables is examined.
