Item Apples(University of Minnesota, 1897) Green, Samuel B.Item Apples and apple growing in Minnesota(University of Minnesota. Agricultural Experiment Station, 1903-07) Green, Samuel B.; University of Minnesota. Horticultural DivisionItem Establishing behavioral correlates: The MMPI as a case study(1982) Green, Samuel B.Two methods have been used to determine MMPI behavioral correlates: the whole-sample and split-sample techniques. The latter technique, which splits a sample into half samples, is currently in use because it ostensibly controls more adequately for Type I errors by requiring significance in both half samples. By simply adjusting the level of significance for the whole-sample approach, however, it can control for Type I errors as well as the split-sample technique. Furthermore, the whole-sample approach appears to control more adequately for Type II errors than the split-sample technique. Finally, data are presented suggesting that as an indicator of the average result obtained by repeated random splittings of a sample, results from the whole-sample approach are preferable to those from a single split of a sample. The whole-sample method was thus recommended; however, the probability of a Type I error for each correlate tested should be set at values smaller than those currently used.Item The expense of the proposed national park for Minnesota(University of Minnesota. Agricultural Experiment Station., 1900) Green, Samuel B.; University of Minnesota, Agricultural Experiment StationItem Forestry in Minnesota(University of Minnesota. Agricultural Experiment Station., 1895) University of Minnesota, Agricultural Experiment Station; Green, Samuel B.Item Garden tillage and implements(University of Minnesota. Agricultural Experiment Station, 1894-12) Green, Samuel B.; University of Minnesota. Horticultural DivisionItem Identifiability of spurious factors using linear factor analysis with binary items(1983) Green, Samuel B.The purpose of this study was to evaluate the robustness of some linear factor analytic techniques to violations of the linearity assumption by factoring product-moment correlations computed from data conforming to an extended, three-parameter logistic model of item responding. Three factors were crossed to yield 81 subcases: the number of underlying dimensions (0, 1, or 2), the number of items (10, 15, 20, 25, 30, 35, 40, 45, or 50), and the number of subjects (100, 250, or 500). The mean eigenvalues for the subcases were evaluated using parallel analysis and the scree technique. The mean eigenvectors were visually inspected. For almost all subcases with one or two underlying dimensions, a single spurious factor was able to be identified using parallel analysis. However, in comparison with the nonspurious factors, it was small in magnitude and, in practice, factors of this relative size might be interpreted as trivial. It was concluded that researchers may have some confidence in interpreting linear factor analysis with binary items if they are using a test instrument that has been carefully developed.Item Itasca State Park as a demonstration forest and forest experiment station.
