Segmented regression analysis can also be performed on multivariate data by partitioning the various independent variables. Segmented regression is useful when the independent variables, clustered into different groups, exhibit different relationships between the variables in these regions. The boundaries between the segments are breakpoints.
The main difference between the two approaches is that the general linear model strictly assumes that the residuals will follow a conditionally normal distribution, [4] while the GLM loosens this assumption and allows for a variety of other distributions from the exponential family for the residuals. [2]
The F-test is computed by dividing the explained variance between groups (e.g., medical recovery differences) by the unexplained variance within the groups. Thus, = If this value is larger than a critical value, we conclude that there is a significant difference between groups.
The aim of such techniques as ANCOVA is to remove the effects of such uncontrolled variation, in order to increase statistical power and to ensure an accurate measurement of the true relationship between independent and dependent variables. [8] An example is provided by the analysis of trend in sea-level by Woodworth (1987). [9]
The difference between the multinomial logit model and numerous other methods, models, algorithms, etc. with the same basic setup (the perceptron algorithm, support vector machines, linear discriminant analysis, etc.) is the procedure for determining (training) the optimal weights/coefficients and the way that the score is interpreted.
