Nonlinear Least Squares Results - Advanced Tab

Purpose of Nonlinear Estimation

Select the Advanced tab of the Nonlinear Least Squares Results dialog box to access the options described here.

Element Name Description
Summary: Parameter estimates Click the Summary: Parameter estimates button to display a spreadsheet with the parameter estimates for the current model. Summary statistics for the current analysis will be displayed in the spreadsheet header.
Predicted values, Residuals, etc Click the Predicted values, Residuals, etc. button to create a spreadsheet containing the observed, predicted, and residual values.
Covars of parameters Click the Covars of parameters button to produce a spreadsheet with the (asymptotic) variance/covariance matrix for the parameter estimates
Correls of parameters Click the Correls of parameters button to create a spreadsheet with the correlations between parameter estimates.
Fitted 2D function and & observed vals Click the Fitted 2D function & observed vals button to produce a 2-dimensional graph of the observed values. This plot enables a 2-dimensional visual examination (i.e., qualitative evaluation) of the fit of the data to the model. It is useful for identification of outliers, which can then be marked in the Data Editor using the Brushing Tool button.
p-value for highlighting Adjust the p-value by entering a new value in the p-value for highlighting box or by using the microscrolls. The default p-value for highlighting is .05. On the summary spreadsheet, STATISTICA will highlight all p-values that are equal to or less than the value specified in this field. For more details on p-value, see Elementary Concepts.
Confidence intervals for parameter estimates Enter a value in the Confidence intervals for parameter estimates box that will be used for constructing confidence limits in the respective results spreadsheets or graphs; by default 95% confidence limits will be constructed.
