Julia 有一个基于 LLVM 的 JIT 编译器,这让使用者无需编写底层的代码也能拥有像 C 与 FORTRAN 那样的性能。因为代码在运行中编译,你可以在 shell 或 REPL 中运行代码,这也是一种推荐的工作流程。 Julia 是动态类型的。并且提供了为并行计算和分布式运算设计的多重派发机制。 Julia 自带包管理器。 Julia 有许多...
虽然Douglass.jl刚写完没多久,jmboehm本人也还在进一步开发,但目前已经可以执行Stata多个主要命令,比如: generate-- Creates a new variable and assigns the output from an expression to it. replace-- Recplaces the content of a variable, but does not change the type. egenerate(oregenfor short) -- Cre...

Linear Regression is a fundamental machine learning algorithm used to predict a numeric dependent variable based on one or more independent variables. The dependent variable (Y) should be continuous.In this tutorial I explain how to build linear regression in Julia, with full-fledged post model-...
