In most studies, the intended (full) data, i.e., the data that the study investigators wish to collect, are inevitably incompletely observed. In modern studies, the full data are typically high dimensional, usually comprising many baseline and timevarying variables. Scientific interest, however, often focuses on some low-dimensional parameter of the(More)
It's coming again, the new collection that this site has. To complete your curiosity, we offer the favorite data analysis by resampling concepts and applications book as the choice today. This is a book that will show you even new to old thing. Forget it; it will be right for you. Well, when you are really dying of data analysis by resampling concepts and(More)
Questions that ask respondents to "choose all that apply" from a set of items occur frequently in surveys. Categorical variables that summarize this type of survey data are called both pick any/c variables and multiple-response categorical variables. It is often of interest to test for independence between two categorical variables. When both categorical(More)
Two experiments were conducted to examine the effects of hot boning, modified atmosphere packaging, and injection enhancement on the oxidative and sensory properties of beef round muscles. The beef knuckle (quadriceps muscles) was partially hot boned within 1.5 h postmortem from one randomly selected side of each beef carcass (n = 14), whereas the(More)
The carriers mineral oil and Silwet L-77 and the botanical insecticides Neemix 4.5 and Hexacide were evaluated for their impacts on the efÞcacy of Beauveria bassiana (Balsamo) Vuillemin conidiaagainst redßourbeetle,Triboliumcastaneum(Herbst), larvae.Thedosagesof liquid treatments were quantiÞed by both conidia concentration in the spray volume and conidia(More)
Survey respondents are often prompted to pick any number of responses from a set of possible responses. Categorical variables that summarize this kind of data are called pick any/c variables. Counts from surveys that contain a pick any/c variable along with a group variable (r levels) and stratification variable (q levels) can be marginally summarized into(More)
Decady and Thomas (2000, Biometrics 56, 893-896) propose a first-order corrected Umesh-Loughin-Scherer statistic to test for association in an r x c contingency table with multiple column responses. Agresti and Liu (1999, Biometrics 55, 936-943) point out that such statistics are not invariant to the arbitrary designation of a zero or one to a positive(More)
The aims of this descriptive study were to examine the prevalence and associations of coprophenomena (involuntary expression of socially unacceptable words or gestures) in individuals with Tourette syndrome. Participant data were obtained from the Tourette Syndrome International Database Consortium. A specialized data collection form was completed for each(More)
Two experiments were conducted to determine the effectiveness of using mechanical probes and objective color measurement on beef LM to predict cooked tenderness. In Exp. 1, sharp needle (SN), sharp blade (SB), blunt needle (BN), blunt blade (BB), and plumb bob (PB) probes were used to measure uncooked LM (n = 29) at 2 d postmortem in both a perpendicular(More)
