出现“stata显示java installation not found”的情况,通常是在使用Stata进行某些功能时,程序无法找到Java环境的安装。解决这一问题的过程包括环境配置、编译过程、参数调优、定制开发、错误集锦和进阶指南。以下是该过程的具体记录。 环境配置 在配置Stata和Java环境时,首先需要确保Java的正确安装,并且将Java的路径添加到系...

We specifiedweeksinmeta forestplot's optioncumulative()to perform cumulative meta-analysis withweeksas the ordering variable. This option is also supported bymeta summarize. The studies are first ordered with respect toweeks, from smallest to largest amount of contact. Then, separate meta-analyses ar...
You can pass suboptions not just to the iv command but to all stage regressions with a comma after the list of stages. Example: reghdfe price (weight=length), absorb(turn) subopt(nocollin) stages(first, eform(exp(beta)) ) By default all stages are saved (seeestimates dir). The sub...
If the explanatory variables are stacked into matrix X, one or more variables (columns) in x are collinear, then X'X is rank deficient. Therefore it cannot be inverted and the OLS estimate of beta = inverse(X'X)X'Y does not exist. In a model in which cross-sectional dependence in ...
具体说, Stata具有如下统计分析能力:参数估计,t检验,单因素和多因素的方差分析,协方差分析,交互效应模型,平衡和非平衡设计,嵌套设计,随机效应,多个均数的两两比较,缺项数据的处理,方差齐性检验,正态性检验,变量变换、参数估计,列联表分析 ( 列联系数,确切概率 ) ,流行病学表格分析等、秩变换,秩和检验,秩相关...
On occasion, I will use an R function that is not available in Stata, such as XGBoost. In these cases I like to create an R environment that aligns with my Stata environment. Similar to Stata, R automatically runs .Rprofile upon launch (if found). This file is typically stored in ...
Introduction Some of the most common Stata commands (collapse, merge, sort, etc.) are not designed for large datasets. This package provides alternative implementations that solves this problem, speeding up these commands by 3x-10x: Other user commands that are very useful for speeding up Stata ...
