I’ve downloaded MLJ pkg, but :

```julia
using MLJ

TransformedTargetModel()

```

```julia
UndefVarError: `TransformedTargetModel` not defined

Stacktrace:
 [1] top-level scope
   @ In[22]:10

```

I don’t know if the function is actually not in this pkg, but I find the function in the introducion of MLJ
