tLocationScaleDistribution t Location-Scale probability distribution object

主题

t Location-Scale Distribution
The t location-scale distribution is useful for modeling data distributions with heavier tails (more prone to outliers) than the normal distribution.
Represent Cauchy Distribution Using t Location-Scale
This example shows how to use the t location-scale probability distribution object to work with a Cauchy distribution with nonstandard parameter values.
