Function for standard deviation and p-value for SAT

[Shicheng-Guo]

Dear Team,

I am curious do we have Function to calculate standard deviation and p-value for ate, something like below:

Predict treatment effect using fitted estimator

ate = meta_reg.predict_ate(X) 

Compute standard errors, confidence intervals, and p-values

cov = meta_reg.covariance_
se = np.sqrt(np.diag(cov))
ci = meta_reg.confidence_intervals_
p = meta_reg.p_values_

Best,

Shicheng
