example/regressions.py throws error

When I try to run python example/regressions.py it throws this error

Traceback (most recent call last):
  File "examples/regressions.py", line 12, in <module>
    dateRange = DatetimeIndex(start, periods=N)
  File "/Users/vyomkesh/code/pandas/pandas/util/decorators.py", line 88, in wrapper
    return func(*args, **kwargs)
  File "/Users/vyomkesh/code/pandas/pandas/tseries/index.py", line 240, in __new__
    data = list(data)
TypeError: 'datetime.datetime' object is not iterable

Looks like using the date_range method fixes the error.

@tvyomkesh Thanks for looking into the examples!

But apart from fixing the examples, I think we should think for a moment what we want to do with these examples. Why do we want them? What is their function?
And depending on that, do we want to update/extend them? Or maybe move them to the docs?

I personally never looked at these examples. And they are also quite outdated. Eg using the ols from pandas is somewhat (unofficially) deprecated for the use of statsmodels, and the finance module in matplotlib is deprecated starting from matplotlib 1.4. And to get such data, I think pandas-datareader should be used.

I think that these should be checked to see if they are in the docs ; if not and appropriate add any
then blow away the entire directory
these are just duplicate, not maintained, not tested and pretty much superfluous to the docs
