samplevar_dataset_to_varcope(samplevar_dataset, sample_size)

Convert “sample variance of the dataset” (variance of the individual observations in a single sample) to “sampling variance” (variance of sampling distribution for the parameter).

Parameters

• samplevar_dataset (array_like) – Sample variance of the dataset (e.g., np.var(values)).

• sample_size (int) – Sample size

Returns

varcope (array_like) – Sampling variance of the parameter

Notes

Sampling variance is sample variance divided by sample size.
