Definitions:

Student t Distribution

A probability distribution that is used to estimate population parameters when the sample size is small and the population variance is unknown.

Parameter v

In statistics, it can refer to a parameter associated with a specific distribution or model, often used to denote degrees of freedom in certain distributions.

Variance V(t)

A statistical measure of the dispersion of a set of data points in a data series around the mean, denoted as V(t) when considering time-series data.

Number

A mathematical object used to count, measure, and label; the basic concept of numbers includes integers, real numbers, and complex numbers.
