離散型態配對資料模型建立探討

吳東霖, Wu, Dong-Lin Unknown Date (has links)
在實務上,複選題分析一直處於觀察樣本情形的階段;至於進行檢定以推估母體情形的過程,則幾乎沒有人考慮到。就算曾經試圖想作類似檢定,卻也常常找不到可供參考的文獻或是使用了不適當的分析方法。 本研究的主要目的在於探討各式各樣離散型態相關資料的分析方法,其中亦包含許多複選題的分析方法。幾乎每個方法皆附上範例來說明程式撰寫及分析過程,希望對有此需求的人能有所幫助。 / Problems with multiple responses are usually analyzed by observing only the sample proportions. People don't bother to make any inferences based on the sample information mostly because they do not know how to do it. Even for those who do go beyond the stage of descriptive statistics might not work it out correctly. In the study, we review statistical methods for analyzing dependent proportions, including multiple responses. Almost every method is supplemented with an example which explains the way a related SAS program is written and the way the output is analyzed and explained. We hope that the results presented here will be helpful to those who are engaged in any analysis of multiple responses.

Microhabitat and Movement Assessment for Northern Mexican Gartersnakes (Thamnophis eques megalops) at Bubbling Ponds Hatchery, Arizona

January 2017 (has links)
abstract: Species conservation requires an understanding of the habitats on which that species depends as well as how it moves within and among those habitats. Knowledge of these spatial and temporal patterns is vital for effective management and research study design. Bubbling Ponds Hatchery in Cornville, Arizona, supports a robust population of the northern Mexican gartersnake (Thamnophis eques megalops), which was listed as threatened under the Endangered Species Act in 2014. Natural resource managers are interested in understanding the ecology of gartersnakes at this site to guide hatchery operations and to serve as a model for habitat creation and restoration. My objectives were to identify habitat selection and activity patterns of northern Mexican gartersnakes at the hatchery and how frequency of monitoring affects study results. I deployed transmitters on 42 individual gartersnakes and documented macro- and microhabitat selection, daily and seasonal activity patterns, and movement distances. Habitat selection and movements were similar between males and females and varied seasonally. During the active season (March–October), snakes primarily selected wetland edge habitat with abundant cover and were more active and moved longer distances than during other parts of the year. Gestating females selected similar locations but with less dense cover. During the inactive season (November–February), snakes were less mobile and selected upland habitats, including rocky slopes with abundant vegetation. Snakes displayed diurnal patterns of activity. Estimates of daily distance traveled decreased with less-frequent monitoring; a sampling interval of once every 24 hours yielded only 53–62% of known daily distances moved during the active season. These results can help inform management activities and research design. Conservation of this species should incorporate a landscape-level approach that includes abundant wetland edge habitat with connected upland areas. Resource managers and researchers should carefully assess timing and frequency of activities in order to meet project objectives. / Dissertation/Thesis / Masters Thesis Applied Biological Sciences 2017

Fúze obchodních korporací a jejich vliv na finanční situaci / Mergers of Business Corporations and Their Influence on Financial Situation

Kubáňová, Andrea January 2016 (has links)
This thesis is concerned with domestic mergers of business corporations realized between 2009 - 2012 and their influence on financial situation of chosen subjects. The first part of my paper describes basic theoretical aspects of mergers including their division and motives leading to the realization and their phases. The second chapter consists of trade-legal and accounting adjustment of mergers. Considering practical part, the main focus is on legal modification valid from 31. 12. 2011 to 1. 1. 2012. Following part of this thesis explains accounting solutions of mergers in example, where the immediate impact is shown on realization of the opening balance sheet. The fourth part is concerned with financial analysis, where the sources, users and relevant methods are mentioned. All analysis and results are submitted and described in the final part of my thesis.

Adjusted Wald Confidence Interval for a Difference of Binomial Proportions Based on Paired Data

Bonett, Douglas G., Price, Robert M. 01 August 2012 (has links)
Adjusted Wald intervals for binomial proportions in one-sample and two-sample designs have been shown to perform about as well as the best available methods. The adjusted Wald intervals are easy to compute and have been incorporated into introductory statistics courses. An adjusted Wald interval for paired binomial proportions is proposed here and is shown to perform as well as the best available methods. A sample size planning formula is presented that should be useful in an introductory statistics course.

Confidence Intervals for a Ratio of Binomial Proportions Based on Paired Data

Bonett, Douglas, Price, Robert M. 15 September 2006 (has links)
Four interval estimation methods for the ratio of marginal binomial proportions are compared in terms of expected interval width and exact coverage probability. Two new methods are proposed that are based on combining two Wilson score intervals. The new methods are easy to compute and perform as well or better than the method recently proposed by Nam and Blackwelder. Two sample size formulas are proposed to approximate the sample size required to achieve an interval estimate with desired confidence level and width.

Statistical Inference for a Ratio of Dispersions Using Paired Samples

Bonett, Douglas G., Seier, Edith 01 January 2003 (has links)
Wilcox (1990) examined the Type I and Type II error rates for several robust tests of H0: σ12/σ22 = 1 in paired-data designs and concluded that a satisfactory solution does not yet exist. A confidence interval for a ratio of correlated mean absolute deviations is derived and performs well in small sample sizes across realistically nonnormal distributions. When used to test a hypothesis, the proposed confidence interval is almost as powerful as the most powerful test examined by Wilcox.
