Download or read book Interval Method to Estimate Lactation Yield written by Oumer Wabe and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: To test the accuracy of 30-day TIM with 15 and 45-day TIM of milk recording to estimate the lactation yield and to measure the effect of genetic group, parity and season of calving on the accuracy, 1220 lactation records of Friesian x Arsi cows were utilized. The lactation yield was estimated for lactation length of 210-305 days. The accuracy was measured in terms of absolute difference and percentage difference between actual and estimated yield. The study revealed that 15, 30 and 45-day time interval can estimate lactation yield accurately to extent of less than five percent bias irrespective of genetic group and parity. The season of calving significantly (P 0.05) affected the percentage difference in 15-day TIM. The lactation yield estimated by 15-day TIM was more accurate with high R2 value 99.62%. The regression analysis indicated that actual yield of 9th period in 15-day, 5th period in 30-day and 3rd period in 45-day TIM predicted reliable estimate of 305-day yield. Thus 30 and 45-day time interval methods of recording can be used in estimation of lactation yield in crossbred cows irrespective of season of calving and parity.

Download or read book Elements of Survey Sampling written by R. Singh and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern statistics consists of methods which help in drawing inferences about the population under consideration. These populations may actually exist, or could be generated by repeated· experimentation. The medium of drawing inferences about the population is the sample, which is a subset of measurements selected from the population. Each measurement in the sample is used for making inferences about the population. The populations and also the methods of sample selection differ from one field of science to the other. Social scientists use surveys tocollectthe sample information, whereas the physical scientists employ the method of experimentation for obtaining this information. This is because in social sciences the factors that cause variation in the measurements on the study variable for the population units can not be controlled, whereas in physical sciences these factors can be controlled, at least to some extent, through proper experimental design. Several excellent books on sampling theory are available in the market. These books discuss the theory of sample surveys in great depth and detail, and are suited to the postgraduate students majoring in statistics. Research workers in the field of sampling methodology can also make use of these books. However, not many suitable books are available, which can be used by the students and researchers in the fields of economics, social sciences, extension education, agriculture, medical sciences, business management, etc. These students and workers usually conduct sample surveys during their research projects.

Download or read book Bayesian Data Analysis Third Edition written by Andrew Gelman and published by CRC Press. This book was released on 2013-11-01 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now in its third edition, this classic book is widely considered the leading text on Bayesian methods, lauded for its accessible, practical approach to analyzing data and solving research problems. Bayesian Data Analysis, Third Edition continues to take an applied approach to analysis using up-to-date Bayesian methods. The authors—all leaders in the statistics community—introduce basic concepts from a data-analytic perspective before presenting advanced methods. Throughout the text, numerous worked examples drawn from real applications and research emphasize the use of Bayesian inference in practice. New to the Third Edition Four new chapters on nonparametric modeling Coverage of weakly informative priors and boundary-avoiding priors Updated discussion of cross-validation and predictive information criteria Improved convergence monitoring and effective sample size calculations for iterative simulation Presentations of Hamiltonian Monte Carlo, variational Bayes, and expectation propagation New and revised software code The book can be used in three different ways. For undergraduate students, it introduces Bayesian inference starting from first principles. For graduate students, the text presents effective current approaches to Bayesian modeling and computation in statistics and related fields. For researchers, it provides an assortment of Bayesian methods in applied statistics. Additional materials, including data sets used in the examples, solutions to selected exercises, and software instructions, are available on the book’s web page.
