.A model where the fit parameters appear linearly in the Least Squares normal equations is known as a “linear model”; otherwise it is “nonlinear”. In many scientific experiments, the regression model has only one or two predictors, and the aim of regression is to fit a curve or a surface to the experimental data.
Most are found under the Statistics->ROC Curves menu: Enter data through manual input into an internal spreadsheet or import data through Excel, SPSS, or several other programs. Under “ROC analysis”, plot a single ROC curve (with optional confidence bounds). The output is a graph, with the optimal cutpoint marked on the graph.
Curve fit on stata CURVEFIT: Stata module to produces curve estimation regression statistics and related plots between two variables for alternative curve estimation regression models. Abstract How can I do a scatterplot with regression line in Stata? | Stata FAQ Stata makes it very easy to create a scatterplot and regression line using the graph twoway command. We will illustrate this using the hsb2 data file.
