This study attempts to assess the financial literacy level of retail individual investors in the state of Gujarat, India and its effect on their investment decision. The data collection instrument consisted of a performance test and questionnaire. The performance test was used to measure the financial literacy level of investors. The median percentage of correct answer of the sample was considered to frame the financial literacy level. Forty-four variables of investment decision were studied. Out of a total of 385 respondents, 39.20% of the respondents are considered investors with a higher level of financial literacy and 60.80% of respondents are considered investors with a relatively lower level of financial literacy. This study found that financial literacy does have a statistically significant effect on the investment decision of investors.  相似文献

In team sports, tactical periodisation refers to the planned manipulation of training loads with the aim of prioritising athlete readiness for matches of greatest importance. Although monitoring of athletes’ physical condition is often used to inform this planning, the direct influence of external factors on match difficulty has not been well quantified. In this study, a ‘match difficulty index’ (MDI) for use in Super Rugby was developed, based on the influence imparted by five external factors on previous match outcomes. Specifically, information relating to match location, days break between matches, time-zone change and opposition ladder position (both current and previous year) were collected for matches played during the 2011–2013 Super Rugby seasons. Logistic regression analyses were used to assess the importance of each of these factors with respect to match outcome (win/loss), with opposition ladder position and match location (home, domestic away or international) exerting the greatest influence on match difficulty. Three separate cross-validated models were constructed, with match outcome classification performance reported as 66.2%, 65.5% and 63.7% respectively. The three MDI models emanating from this study can each be used to inform tactical periodisation program design both prior to and during the regular season.  相似文献

基于安徽省1995-2013年的年度数据,首先采用主成分分析法从选取的多维变量中得到代表变量信息的主要因素,以消除解释变量间的多重共线性。其次通过回归分析法对影响安徽省服务贸易的因素进行实证分析。结果显示:安徽省人均GDP、安徽省货物贸易进出口额、安徽省实际利用外资金额、人力资本、安徽省服务贸易开放度、安徽省居民消费价格指数、安徽省城市化水平和汇率均与服务贸易额呈正相关。并在此基础上提出发展安徽省服务贸易的对策建议。  相似文献

Since the controversial finding of the Coleman Report (1966), which was that school resources had little effect on educational outcomes comparing to family background, huge literature has emerged in order to verify the above finding in countries other than the United States. The Heyneman–Loxley work (1983) presented for the first time clear evidence that variation in school resource quality could matter more than variation in family inputs in low and middle income countries. Following this literature, and using TIMSS 2007 data, we attempt in this study to revisit the Heyneman–Loxley hypothesis and the related debate regarding the overall importance of schools in explaining variations in student achievement across Middle East and North African countries. Survey Jackknife regression technique and quantile regressions have been used for the purpose of this study. Our results are in line with those of Baker et al. (2002) showing that the Heyneman–Loxley effect had declined over time.  相似文献

A multilevel logistic model for estimating a nonlinear trajectory in a multiple-baseline design is introduced. The model is applied to data from a real multiple-baseline design study to demonstrate interpretation of relevant parameters. A simple change-in-levels (ΔLevels) model and a model involving a quadratic function (Quadratic) for the nonlinear intervention phase data were also estimated. In addition, a simulation study was conducted to assess Markov chain Monte Carlo estimation of the logistic model and compare its trajectory recovery with use of the ΔLevels and Quadratic models. While most of the logistic model's parameter values were recovered well, trajectory recovery was very reasonable using the simpler Quadratic model. Results are discussed along with recommendations for practitioners and directions for future research.  相似文献

目前商业银行面临的个人信用风险问题极其复杂,如何对个人信用风险进行管理非常重要。个人信用风险建模是其中很关键的一步。利用某商业银行信用卡数据,构建信用评分模型,预测客户的违约概率。通过采用ROSE(random over sampling examples)方法处理类别不均衡的问题,利用Group-Lasso(AUC准则)方法进行变量选择,构建基于Logistic回归的信用评分模型。实证结果表明,该方法对样本数据进行类别不均衡处理的结果比其他模型在判别能力和预测能力上更为有效。采用该方法所构建的模型能够作为客户信用评价决策的有效依据,指导银行及其他金融机构评估顾客个人信用风险,在实际运用中具有良好的可操作性。  相似文献

基于推拉理论的农民工定居地选择意愿的实证研究   总被引:2,自引:0,他引:2  
首先运用推拉理论从理论上分析哪些因素影响农民工定居地选择意愿,然后利用河南省汝州市187个外出打工农民样本数据,运用Logistic模型分析方法,进行实证检验。结果显示,农民工收入越高和年龄越小越倾向于在打工城市定居;外地人子女入学受歧视和老家经营的耕地面积大,倾向于回农村老家定居;打工城市为省会城市、直辖市和中心镇与对照组地级市或县城比较,在打工城市定居的意愿会下降;打工城市位于东部或是西部地区较对照组中部地区比较,在打工城市定居的意愿也会下降。最后,提出了相关建议。  相似文献
