firms. However, the problem is that each variable is in a different excel file and that too in a wide format. I can transfer these files into stata format using stat transfer. Could anyone please tell me if its possible to convert these multiple data files into one datafile in the panel ...
调整前后宽度-> long -> Wide 调整前后宽度是指在前端开发中调整元素的宽度,使其适应不同的屏幕尺寸或布局需求。通过调整元素的宽度,可以实现页面的响应式布局,提供更好的用户体验。 在前端开发中,调整前后宽度通常通过CSS来实现。可以使用CSS的属性和单位来设置元素的宽度,如width、max-width、min-width等。通过设...
Stata means "reshape to wide" when it says "reshape wide" and similarly for "long". In your case, the example data appear to be already in long form with identifier repeated for each observation. For most panel or longitudinal tasks, this is what you need, so if I understand you ...

Physical geography has long been identified as critical for urban development, land use and environmental outcomes in cities worldwide. However, the literature has yet to provide comprehensive, quantitative analyses of the global extent and impact of urban geographic barriers. Here we introduce three ...

因为我们没有在命令中指定性别,所以Stata假定它在逻辑观察中是恒定的,这里是id。 Wide and long data forms 将数据视为样本Xij的集合,其中i是逻辑观察或组标识符,j是子观察或组内标识符。通过逻辑观察来组织宽格式数据,将所有数据存储在一行中的特定观察上。 通过子观察组织长格式数据,将数据存储在多行中。
