比如宏X的值是数字12,进入mata以后就变成字符12了,也就是说这个时候不能进行数值运算了。 看完输入,再来看看怎么输出。 输出成一个变量最麻烦,需要用到两个命令:st_addvar()和st_store()。比如mata中有一个矩阵N*K的矩阵Y,现在将其输出到Stata中,类型为“long”,并取名为X1,X2,...,XK。比如K=3,那么...

The function is defined on the plane that is spanned by these two axes. You can define and visualize this function as follows: 1. First, create vectors with the desired resolution: >> x1=0:4; x2=0:5; 2. Next, define the function on these ...
To PIN of a mobile phone is a four-digit number ( eg 2527 or 0592 ), how many different PINs can be defined if the last digit may be " 0" or may have two consecutive zeros? Given two variables x and y, what does Corr(x, y) = 0 mean?...
