Python Multiple Linear Regression using OLS code with specific data?

Question

I am using the ols.py code downloaded at scipy Cookbook (the download is in the first paragraph with the bold OLS) but I need to understand rather than using ra

Answer 1

the ols function takes the entire independent data set as the second argument. Try

m = ols(y, [x1, x2, x3], ...)

though I suspect you may need to wrap it in numpy arrays:

x = numpy.ndarray([3, len(x1)])
x[0] = numpy.array(x1)
x[1] = numpy.array(x2)
x[2] = numpy.array(x3)
m = ols(y, x, ...)
