fusional language

in linguistic typology, a language that forms words by the fusion (rather than the agglutination) of morphemes, so that the constituent elements of a word are not kept distinct. Fusional languages, such as Latin and Greek, tend to have numerous grammatical inflections, with each form serving several distinct functions. Also called synthetic language. Compare agglutinative language; isolating language.

regression sum of squares

(symbol: SS_regression) a number indicating the amount of variance in a dependent variable that can be explained by the variance in one or more associated independent variables. It thus describes how well a particular model fits the observed data. For example, in linear regression it is used to calculate a coefficient of determination or a coefficient of multiple determination, and in analysis of variance it is used to determine the total sum of squares and calculate an F ratio. Compare error sum of squares.
