You should try to find specific names for your variables that uniquely identify the referred object. Names like variable, data, or value may be too generic. While these names can work for short examples, they’r
Thereshape consvariables include those variables that (1) uniquely identify the subjects, and (2) do not vary within subject but that you want carried along. To fix the problem on our end, we should changereshapeso that list (1) is given with some newreshape idcommand, which would continu...
id year do not uniquely identify observations in the using data,可能是因为使用的数据表中,同一个id和year出现了两次,可到excel中新开一列使用=id&year将id和year合并然后使用条件格式突出重复值删除掉多余的。 *2.mergemany *1 若存在onetow,threefour,five,six多个xlsx数据库,数据库中均有id和year列...
Energy models are used to illustrate, calculate and evaluate energy futures under given assumptions. The results of energy models are energy scenarios representing uncertain energy futures. The discussed approach for uncertainty quantification and evalua
Equally, for mobile organisms a reliable absence during a weeklong survey does not imply absence in that year. Hierarchical statistical models, often using Bayesian approaches, have been developed specifically to address the cross-type and cross-scale nature of occurrence data and used to combine ...
