Cameron is exactly right. These two forms are exactly equivalent:

```julia
julia> using StatsModels

julia> (Term(:y) ~ Term(:x1) + Term(:x2)) == @formula(y ~ x1 + x2)
true

```

As @nilshg pointed out in [this post](https://discourse.julialang.org/t/using-all-independent-variables-with-formula-in-a-multiple-linear-model/43691/5), this is actually the expression that’s generated by the formula macro:

```julia
julia> @macroexpand @formula(y ~ x1 + x2)
:(StatsModels.Term(:y) ~ StatsModels.Term(:x1) + StatsModels.Term(:x2))

```
