[julia-users] Re: linreg strangely picky about inputs

[Steven G. Johnson]

I think it's an error.  The method definition should probably just be:

linreg{T<:Number,S<:Number}(X::AbstractVector{T}, y::AbstractVector{S}) = 
[ones(T, size(X,1)) X] \ y

which will allow it to work for X and y of different types.

A PR (pull request) with a patch and a test case would be most welcome.
