stata状态下,matsize最大是11000,mata状态下,没有这个限制。mata还有大量stata没有的函数与运算(特别是针对矩阵的)。 Description Mata is a component of Stata. It is a matrix programming language that can be used interactively or as an extension for do-files and ado-files. Thus 1. Mata can be ...
square, diagonal matrix created from the row or column vector the number of zeros on the diagonal of M s[floor(i),floor(j)], the i, j element of the matrix named s; missing if i or j are out of range or if matrix s does not exist a copy of Stata internal system matrix ...

I have heard that R is best for network data, but right now using Stata, I created a variable for each individual and then I am running an if statement that looks in the [_n+x] cell for the individual in the given column and places a one. I was then going to aggregate these data...
My question is related to differing results for correlation matrices. I have run correlations based on mental health measure scores for couples in both Stata and in MPlus. However, I get vastly different results for these. I have 340 couples with no missing data. I have checked the data...
By conducting numerical studies, we verify that the obtained Bartlett correction can perform well even when the assumption of normality is violated.C.MatsumotoandH.YanagiharaandH.WakakiJournal of Statal Planning and Inference
Begg’s funnel plot and assessment of Egger’s test (P < 0.05 was regarded as representative of statistical significance). Statistical analyses were done in ORGGASMA, metan and metagen in STATA software, version 11.0 (STATA Corp., College Station, TX, USA) and all tests were two-sided...
Power calculations were conducted using the Stata 15 “power”’ package (StataCorp LLC, College Station, TX). The effective population size was calculated per each locus, aggregating the effective population sizes of each cohort participating in the meta-analyses, using this equation: ...
