Consider a fixed effects ANOVi\ model. We propose to estimate cell means /lij by MLE's ~ij instead of cell averages ~j, and we propose to estimate error variance by a MLEQ2 rather than the usual mean square for error. Even so, much of the usual ANOVi\ methodology carries over when applied to the ~ij 's, and the efficiency is often increased. When this is generalized to common random effects and...
A revised Bayesian algorithm for estimating surface rain rate, convective rain proportion, and latent heating profiles from satellite-borne passive microwave radiometer observations over ocean backgrounds is described. The algorithm searches a large database of cloud-radiative model simulations to find cloud profiles that are radiatively consistent with a given set of microwave radiance measure...
The present study aims to predict procrastination through cognitive errors and perfectionism. The present research method is a descriptive correlation. The statistical population included all high school students in the east of Tehran in the academic year 1393-94, among whom 280 were selected by Simple Random Sampling. To collect data, the negative cognitive errors questionnaire (Leitenberg et ...
this study aims to undertake a statistical study to evaluate the accuracy of nine models that have been previously proposed for estimating the ultimate resistance of plate girders subjected to patch loading. for each model, mean errors and standard errors, as well as the probability of underestimating or overestimating patch load resistance, are estimated and the resultant values are compared o...
We provide methods for transforming an encryption scheme susceptible to decryption errors into one that is immune to these errors. Immunity to decryption errors is vital when constructing nonmalleable and chosen ciphertext secure encryption schemes via current techniques; in addition, it may help defend against certain cryptanalytic techniques, such as the attack of Proos [36] on the NTRU schem...
BACKGROUND As in any measurement process, a certain amount of error may be expected in routine population surveillance operations such as those in demographic surveillance sites (DSSs). Vital events are likely to be missed and errors made no matter what method of data capture is used or what quality control procedures are in place. The extent to which random errors in large, longitudinal datase...
