Incorporates a known value into the linear predictor. For example for linear link the response is given by
y = offset+xß
Weight
Incorporates a known weight for each observation. A value of zero removes the observation from the analysis.
Convergence
The number of iterations of the fitting algorithm may be set. The default of 10 is normally sufficient but some data may require an increase. Failure to fit in 10 iterations usually means that something is wrong. For example your parameter estimates may be converging to + or - infinity. The convergence tolerance specifies the relative change in the deviance below which it is considered that the model has converged. Reducing this value results in more accurate estimates but may result in failure to converge. The default value represents a good compromise.
Alias tolerance
Determines the tolerance used in determining whether a parameter is aliased. Decreasing this value makes it less likely that a parameter will be aliased.
Residuals
Residuals may be determined using the following methods:
d(i) is the contribution to the deviance by observation i
Fit
Fits the model.
Use command-click (non-contiguous selection) or shift-click (contiguous selection) to select columns from list and then add these to the model using Add * (adds all hierachial models) or Add (adds the terms singly). To remove terms from a model select them and click remove.
Include constant
This causes a constant term to be included. Unchecking this box causes the constant to be removed. In terms of linear regression this causes the line to be fitted through the origin. If you have included a factor then a constant term will be include anyway.
Estimates
Displays estimates and standard errors for the current model with p-values if these are selected in the preferences.
Residuals
Displays residuals for the current model. (Calculated using the method specified in the Define dialog)
Corr
Displays the correlation matrix for the currently fitted parameters.
Status
Displays current model settings and convergence parameters.
