Scedasticity - definition(s)

Scedasticity - the relationship between the value of input variables and the variation (rather than the mean) of the output. Where variation changes with the input variable (for example, variation increases over time) then the process demonstrates hetero-scedasticity. Where variation is constant the process demonstrates homo-scedasticity.
