nitishp25: can someone tell me why this fails?
percygautam: Hi @nitishp25 , I think you have to change the test_bfmi() function of test_diagnostics.py. Run the code in test function with updated ddof value and replace the result with the previous value.
nitishp25: Got it, thanks @percygautam!
nitishp25: Ready to merge.
OriolAbril: Also, this is a little unrelated but it would be great if you could fix it. I have just seen that [bfmi docs](https://arviz-devs.github.io/arviz/generated/arviz.bfmi.html#arviz.bfmi) are not rendered properly (see [rhat docs](https://arviz-devs.github.io/arviz/generated/arviz.rhat.html#arviz.rhat) to see how they should look like) there is no `Out` section even though there should be and the `In []` is not properly highlighted. A white line between [lines 48 and 49](https://github.com/arviz-devs/arviz/blob/c3158613f9e793902eddd0e5ecd715595c31c824/arviz/stats/diagnostics.py#L48) should fix this.

Got it. Working on it.
sethaxen: This looks like the right fix. With the fix to the else statement suggested by @OriolAbril, this looks good to me. Thanks for the PR!
nitishp25: Please review @OriolAbril

Incorrect denominator in bfmi
The original equation for `bfmi` is at the bottom of page 7 in [this paper](https://arxiv.org/pdf/1604.00695v1.pdf). The numerator in numpy for a vector `E` is `(length(E) - 1) * np.mean(np.square(np.diff(E)))`. The denominator is `(length(E) - 1) * np.var(E, ddof = 1)`. The two scaling factors cancel and we get
```python
def bfmi(E):
    return np.mean(np.square(np.diff(E))) / np.var(E, ddof = 1)
```
The current implementation uses `ddof=0`, so it's off from the equation in the paper by `length(E) / (length(E) - 1)`

**Additional context**
PyStan's implementation [here](https://github.com/stan-dev/pystan/blob/cbc5c0fc8597504776c08a138adc9ae63329e6a1/pystan/diagnostics.py#L213-L217) is equivalent to the paper's. RStan's implementation of `get_bfmi` [here](https://rdrr.io/cran/rstan/src/R/check_hmc_diagnostics.R) has a different implementation than either ArviZ's current one or PyStan's. Theirs amounts to the original paper's equation multiplied by `(length(E) - 1) / length(E)`.
