scipystatstcdfx
scipystatstcdfx is a function within the SciPy library, specifically part of the scipy.stats module. It is designed to calculate the cumulative distribution function (CDF) of the Student's t-distribution. The Student's t-distribution is a probability distribution that arises in statistical inference and is commonly used for hypothesis testing when the sample size is small and the population standard deviation is unknown.
The tcdfx function takes the observed value (x) as its primary input. It also requires the degrees
