# Tutorial objectives¶

*Estimated timing of tutorial: 20 min*

This is tutorial 3 on our day of examining causality. Below is the high level outline of what we’ll cover today, with the sections we will focus on in this notebook in bold:

Master definitions of causality

Understand that estimating causality is possible

Learn 4 different methods and understand when they fail

perturbations

correlations

**simultaneous fitting/regression**instrumental variables

## Notebook 3 objectives¶

In tutorial 2 we explored correlation as an approximation for causation and learned that correlation \(\neq\) causation for larger networks. However, computing correlations is a rather simple approach, and you may be wondering: will more sophisticated techniques allow us to better estimate causality? Can’t we control things?

Here we’ll use some common advanced (but controversial) methods that estimate causality from observational data. These methods rely on fitting a function to our data directly, instead of trying to use perturbations or correlations. Since we have the full closed-form equation of our system, we can try these methods and see how well they work in estimating causal connectivity when there are no perturbations. Specifically, we will:

Learn about more advanced (but also controversial) techniques for estimating causality

conditional probabilities (

**regression**)

Explore limitations and failure modes

understand the problem of

**omitted variable bias**

# Section 1: Regression: recovering connectivity by model fitting¶

## Video 1: Regression approach¶

You may be familiar with the idea that correlation only implies causation when there are no hidden *confounders*. This aligns with our intuition that correlation only implies causality when no alternative variables could explain away a correlation.

**A confounding example**:
Suppose you observe that people who sleep more do better in school. It’s a nice correlation. But what else could explain it? Maybe people who sleep more are richer, don’t work a second job, and have time to actually do homework. If you want to ask if sleep *causes* better grades, and want to answer that with correlations, you have to control for all possible confounds.

A confound is any variable that affects both the outcome and your original covariate. In our example, confounds are things that affect both sleep and grades.

**Controlling for a confound**:
Confonds can be controlled for by adding them as covariates in a regression. But for your coefficients to be causal effects, you need three things:

**All**confounds are included as covariatesYour regression assumes the same mathematical form of how covariates relate to outcomes (linear, GLM, etc.)

No covariates are caused

*by*both the treatment (original variable) and the outcome. These are colliders; we won’t introduce it today (but Google it on your own time! Colliders are very counterintuitive.)

In the real world it is very hard to guarantee these conditions are met. In the brain it’s even harder (as we can’t measure all neurons). Luckily today we simulated the system ourselves.

## Video 2: Fitting a GLM¶

Recall that in our system each neuron effects every other via:

where \(\sigma\) is our sigmoid nonlinearity from before: \(\sigma(x) = \frac{1}{1 + e^{-x}}\)

Our system is a closed system, too, so there are no omitted variables. The regression coefficients should be the causal effect. Are they?

We will use a regression approach to estimate the causal influence of all neurons to neuron #1. Specifically, we will use linear regression to determine the \(A\) in:

where \(\sigma^{-1}\) is the inverse sigmoid transformation, also sometimes referred to as the **logit** transformation: \(\sigma^{-1}(x) = \log(\frac{x}{1-x})\).

Let \(W\) be the \(\vec{x}_t\) values, up to the second-to-last timestep \(T-1\):

Let \(Y\) be the \(\vec{x}_{t+1}\) values for a selected neuron, indexed by \(i\), starting from the second timestep up to the last timestep \(T\):

You will then fit the following model:

where \(V\) is the \(n \times 1\) coefficient matrix of this regression, which will be the estimated connectivity matrix between the selected neuron and the rest of the neurons.

**Review**: As you learned in Week 1, *lasso* a.k.a. **\(L_1\) regularization** causes the coefficients to be sparse, containing mostly zeros. Think about why we want this here.

## Coding Exercise 1: Use linear regression plus lasso to estimate causal connectivities¶

You will now create a function to fit the above regression model and V. We will then call this function to examine how close the regression vs the correlation is to true causality.

**Code**:

You’ll notice that we’ve transposed both \(Y\) and \(W\) here and in the code we’ve already provided below. Why is that?

This is because the machine learning models provided in scikit-learn expect the *rows* of the input data to be the observations, while the *columns* are the variables. We have that inverted in our definitions of \(Y\) and \(W\), with the timesteps of our system (the observations) as the columns. So we transpose both matrices to make the matrix orientation correct for scikit-learn.

Because of the abstraction provided by scikit-learn, fitting this regression will just be a call to initialize the

`Lasso()`

estimator and a call to the`fit()`

functionUse the following hyperparameters for the

`Lasso`

estimator:`alpha = 0.01`

`fit_intercept = False`

How do we obtain \(V\) from the fitted model?

We will use the helper function `logit`

.

def get_regression_estimate(X, neuron_idx):

return V
# Set parameters

timesteps = 10000 # the number of timesteps to take
random_state = 42
neuron_idx = 1
# Set up system and simulate
A = create_connectivity(n_neurons, random_state)
X = simulate_neurons(A, timesteps)
# Estimate causality with regression
V = get_regression_estimate(X, neuron_idx)
print("Regression: correlation of estimated connectivity with true connectivity: {:.3f}".format(np.corrcoef(A[neuron_idx, :], V)[1, 0]))
print("Lagged correlation of estimated connectivity with true connectivity: {:.3f}".format(get_sys_corr(n_neurons, timesteps, random_state, neuron_idx=neuron_idx)))
```

You should find that using regression, our estimated connectivity matrix has a correlation of \(0.865\) with the true connectivity matrix. With correlation, our estimated connectivity matrix has a correlation of \(0.703\) with the true connectivity matrix.

We can see from these numbers that multiple regression is better than simple correlation for estimating connectivity.

# Section 2: Partially Observed Systems¶

*Estimated timing to here from start of tutorial: 10 min*

If we are unable to observe the entire system, **omitted variable bias** becomes a problem. If we don’t have access to all the neurons, and so therefore can’t control them, can we still estimate the causal effect accurately?

## Video 3: Omitted variable bias¶

**Video correction**: the labels “connectivity from”/”connectivity to” are swapped in the video but fixed in the figures/demos below

We first visualize different subsets of the connectivity matrix when we observe 75% of the neurons vs 25%.

Recall the meaning of entries in our connectivity matrix: \(A[i,j] = 1\) means a connectivity **from** neuron \(i\) **to** neuron \(j\) with strength \(1\).
