Abstract: The methodology of experimentation, randomization, and statistical analysis in weather modification has many parallels in clinical trials, such as the need for randomization, and the question of inclusion or exclusion of ...

Abstract: The biplot is a graphical display of a two-dimensional approximation to a matrix. Its usefulness in the display and analysis of matrices of meteorological data is demonstrated by a detailed exposition of two illustrations ...

Abstract: A variety of ratio statistics has been used in the design and evaluation of weather modification experiments and their significance has usually been estimated by rerandomization. These ratios, and especially their logarithms, ...

Abstract: A recent critique of the Climax cloud seeding experiments has raised many issues, which may cast doubt on the validity of those experiments? results. An attempt is made here to clarify the importance of these issues in the ...

Abstract: As a complement to the study by Silverman et al, (1981, this issue), the relative variability of rainfall estimates was studied for randomly located gages. This simplistic model allows for more random variability than ...

Abstract: The use of confidence intervals for assessing the results of weather modification experiments is demonstrated and is shown to be more informative than tests of significance. Multivariate tests, confidence regions, and ...

Abstract: Cloud seeding operations are often evaluated by comparing precipitation during operations with records of previous ?historical? precipitation. Possible biases that can arise from such comparisons have been discussed ...

Abstract: This paper reports separate analyses of daytime and nighttime precipitation based on data from recording raingages of the second Israeli randomized experiment. These analyses seemed important because there are a number of ...
