pyrcmip.stats.get_skewed_normal(median, lower, upper, conf, input_data)

Get skewed normal distribution matching the inputs

Parameters

  • median (float) – Median of the output distribution

  • lower (float) – Lower bound of the confidence interval

  • upper (float) – Upper bound of the confidence interval

  • conf (float) – Confidence associated with the interval [lower, upper] e.g. 0.66 would mean that [lower, upper] defines the 66% confidence range

  • input_data (np.ndarray) – Points from the derived distribution to return. For each point, Y, in input_data, we determine the value at which a cumulative probability of Y is achieved. As a result, all values in input_data must be in the range [0, 1]. Hence if you want a random sample from the derived skewed normal, simply make input_data equal to a random sample of the uniform distribution [0, 1]

Returns

Points sampled from the derived skewed normal distribution based on input_data

Return type

np.ndarray
