Oct 14, · I know of a two-line solution mat b = e(b) local bw = b[1,1] and I too would be interested to hear of a shorter one. Nick [email protected] Claire Kamp Dush I am sure someone had to have asked this type of question before, but in my googling and searching of the statalist archive, I could not come across a clear answer. Oddly, Stata does recognize display X [1, precip]. And Stata would know what I'm trying to do if instead of precip I used the column number where precip appears in the X vector. If I were just doing this operation once, no problem. But I need to do this operation several times. Jul 05, · Extracting specific elements from a matrix. Hi, I need to extract the first element of a matrix of coefficients and store it on a variable, and repeat the process i times. I can set up the for loop.

Jul 05, · Vectors are not really part of Stata parlance, I am afraid, which may well be a shock for those who previously used other products. Extracting specific elements from a matrix Hi, I need to extract the first element of a matrix of coefficients and store it on a variable, and repeat the process i times. I can set up the for loop and do the. Sep 30, · Maarten is right, this is the case for all "special" matrix that Stata returns, you cannot directly display its elements. However, there is an alternative way of doing that (instead of generating a new matrix), using el() function as suggested William Lisowski in this post. Oddly, Stata does recognize display X [1, precip]. And Stata would know what I'm trying to do if instead of precip I used the column number where precip appears in the X vector. If I were just doing this operation once, no problem. But I need to do this operation several times. Stata’s deﬁnition of a matrix includes a few details that go beyond the mathematics.

The Matrix matrix A = (2,1\3,2\-2,2) matrix list A A[3,2] c1 c2 r1 2 1 r2 3 2 r3 -2 2. Multiplication by a Scalar mat B = 3*A mat lis B B[3,2] c1 c2 r1 6 3 r2 9 6 r3 -6 6. Matrix Addition & Subtraction. You can access all current r() elements via return list and the e() elements via ereturn list. A single element of the list can be addressed just by its name. Thus, display e(N) will yield the number of cases in the last estimation, or you may use e(N) as an expression in a computation (where it will be replaced by the number stored in e(N)). Matrix Commands in Stata Stata’s matrix commands are very easy (and can always be referenced in the matrix section of the Stata manual in the library or interactively by typing “help.To learn how to do this, see. help matrix extraction Nick On Fri, Jul 22, display > (output omitted) > >. nlcom (R2: [num]_b[2.r]/[den]_b[2.r]). Here we have a 3 × 2 matrix named A containing elements 1, 2, 3, 4, 5, and 6. Row 1, column 2 .. matrix list displays the matrix with its row and column names. Matrix manipulations have been greatly enhanced since Stata 9 using the Mata language. One of the capabilities is an element-by-element calculation using the . How do I -display- elements of a matrix, such as e(b)? display e(b) is "invalid syntax" while Stata 14 responds to display e(b)[1,1] with "matrix. I know of a two-line solution mat b = e(b) local bw = b[1,1] and I too would be interested to hear of a shorter one.
