tfma.types.ValueWithTDistribution

Represents the t-distribution value.

It includes sample_mean, sample_standard_deviation, sample_degrees_of_freedom. And also unsampled_value is also stored here to record the value calculated without bootstrapping. The sample_standarddeviation is calculated as: \sqrt{ \frac{1}{N-1} \sum{i=1}^{N}{(x_i - \bar{x})^2} }

sample_mean A namedtuple alias for field number 0
sample_standard_deviation A namedtuple alias for field number 1
sample_degrees_of_freedom A namedtuple alias for field number 2
unsampled_value A namedtuple alias for field number 3
