<p>我想做一个四行三列的表格. 与是GEN 了如下三列数据. </p><p>gen concentration_ratio="1-firm concentration ratio"<br/>replace concentration_ratio="2-firm concentration ratio"<br/>replace concentration_ratio="3-firm concentration ratio"<br/>replace concentration_ratio="4-firm concentration ratio"</p><p>gen short_acting=n_ratio if s_m_p==1 &amp; ind==1<br/>replace short_acting=n_ratio if s_m_p==1 &amp; ind==2<br/>replace short_acting=n_ratio if s_m_p==1 &amp; ind==3<br/>replace short_acting=n_ratio if s_m_p==1 &amp; ind==4</p><p></p><p>gen premixed=n_ratio if s_m_p==3 &amp; ind==1<br/>replace premixed=n_ratio if s_m_p==3 &amp; ind==2<br/>replace premixed=n_ratio if s_m_p==3 &amp; ind==3<br/>replace premixed=n_ratio if s_m_p==3 &amp; ind==4</p><p>当我用如下TABLE 命令书出结果时, STATA提示 INVALID SYNTAX.&nbsp; <br/>table concentration_ratio, cont( short_acting&nbsp; premixed)</p><p>看来只有改成 table concentration_ratio, cont(mean short_acting mean premixed) 才行. 但结果输出的是一行3列的表格, 2 个数分别是两列4 个数量的均值</p><p>有没有办法不计算STATISTICS, 直接输出数值啊?<br/>亟待回复, 谢谢!</p>
