这项分析是在控制了LSOA(下层超级输出区)不随时间变化的特征和年份固定效应之后进行的。 下面图C1的Panel A揭示了数字化转换与儿童固有特征之间的直接关联。在进行的多项计量模型分析中,我们将儿童的固有特征设为因变量,而自变量是一个指示变量,当儿童所在的LSOA在调查访问时已完成数字化转换时,该变量取值为1,否则...

tobalance并不是stata内置的命令,需要安装才能进行使用。目前主要有以下安装途径:(1)通过码云(后期完成后设成超链接)下载tobalance.ado文件;(2)ssc install tobalance(后期完成后设定)。 tobalance的语法格式:tobalance [, options] 其中option选项有idvar(varlist)、timevar(varlist)、range(numlist) 、miss(var...

study of balance training using the same outcome measure [17]. A two-sidedttest was used with the level of significance set at .05, with 80% power, and with an assumption of a dropout of 20%. The calculations were performed using Stata version 15 (StataCorp, College Station, TX, USA)...
Nonetheless, using longitudinal data from the German Socio-Economic Panel Study (SOEP), Busch-Heizmann and Holst [44] found a higher prevalence of interference between work and family life among working women than men in Netherland. Gutek et al. [33] attributed some of the reasons to the ...
First, using a panel threshold model, it investigates the impact of OBS on banks' efficiency in China and theoretically analyzes the nonlinear relationship between them. Second, in times of high uncertainty, macroeconomic factors are more critical than bank characteristics in determining the association...
Sample size was calculated using Stata SE 14.2 software by the command “sampicc p1(0.9) number of replicates (4), CI level (95%), specified width (0.14)” (Clark et al., 2010). The study was carried out at the physical therapy research center of the University of Social Welfare and...
The use of panel data helps to control potential sources of unobserved heterogeneity [80,81]. When establishing empirical analysis models, the number of invention patent applications is usually used as a proxy for innovation [60], with the characteristic of being non-negative count data, and the...
It starts with a panel in which one can choose the balancing test to be performed. Once selected, there is an area in which to enter the user data; a nickname or pseudonym is preferred for data protection. In each field, the cm of deviation of the test is indicated, and at the end...
