level2_probability#
- level2_probability(data, outcome)[source]#
Return the outcome probability mean and variance.
- Parameters:
data (Dict[str, any]) â A data dict containing count data.
outcome (str) â bitstring for desired outcome probability.
- Returns:
- (p_mean, p_var) of the probability mean and variance
estimated from the counts.
- Return type:
tuple
Note
This assumes a binomial distribution where \(K\) counts of the desired outcome from \(N\) shots the mean probability is \(p = K / N\) and the variance is \(\sigma^2 = p (1-p) / N\).
