Parameter stability tests indeed check if the parameters of a model remain constant over the sample. The Chow test and predictive failure tests, including both backward and forward versions, are specific methodologies used to assess this stability. While these tests do relate to the broader context of model assumptions in regression analysis, they specifically target the constancy of model parameters over time or across different subsets of data, rather than directly examining all classical linear regression model assumptions.
