Warnings using causal.model

[Manwithoutmind]

When using causal model, I've got warnings:

"the default of observed=False is deprecated and will be changed to True in a future version of pandas..."
in causal_estimator.py line 266. After adding keyword "oberved=True" warning disappear

In a second
"due to key in a future will be use as labels : use ser.iloc[0]"
in regression_estimator.py line 131 after change parameter = self.model.params[0] with self.model.params.iloc[0] warning disappear.

Am I true, I'm not certain, but the job was done....

thanks for noting these @Manwithoutmind
will be great if you can add a pull request with these changes?
For the first issue, since the default was observed=False, shall we keep the same one?

Hi Amit-sharma.
OK I will add a pull request (I just need to have a look to the HowTo...)

For the first issue, in some days the default will be observed=True... (but when ?) and It's look a little stupid to change it now.
But, without doing it, I get a lot of warning and can't read anything on my screen, so.... (maybe change it a little bit the code with testing the version newest/oldest of Pandas ???)
