Start a new project and import the data set ? Use the workset wizard to guide through building the workset and fitting the model ? Generate the report writer to walk through the model results and interpretation ? When displaying SimcaP plots always use the Analysis adviser to guide you. Workset wizard on ON Workset wizard Autotransform variables To transform all variables if any needed, mark the check box Automatic creation of classes for classification or discrimination Selection and Fit of model Report writer Walks you through the model results with interpretation : File | Generate Report Steps in Using SIMCAP, Advanced Mode ? Start a new project and import the data set ? Explore and preprocess the data ? Make working copy of selected data (workset) for model building ? Specify model type and fit it to the workset ? Review fit (plots, diagnostics, coefficients, etc.) ? Predictions ? Generate Report 1a. File New Starting a new project ? Select the data file containing the raw data of the project – directory, file type (XLS, DIF, TXT, …..), file name ? A Wizard opens (see next page) allowing you to specify (optionally) the row containing the Variable names, and (optionally) the columns with the Obs. Numbers and Names ? Here (Commands) you can also do additional things such as – transposing the input data matrix ? Use simple mode with workset wizard ? At the last Wizard page, you can (optionally) specify another name and directory for the project. ? A map of the missing data is shown ? The Wizard finishes and puts you in the Simcawindow ? A starting work set (M1, all data, all Xs, UV scaled) is ready 1b. The second screen of the Wizard 2. Looking at the data ? With the data set table open (Data set edit): ? Quick Info (both var and obs windows can be open) – variables – observations ? Moving the cursor in the data set table up and down, or sidewise, changes the displayed variable and observation ? In the quick info options you can specify what you want to look at (histograms, autocorrelations, …), as well as which items should be the basis for the plots View variables or Observations, Trim, etc. Quick Info 3. Prepare a work copy: The Workset Simple Mode with guidance, or Advanced Mode ? In Workset, you prepare a working copy of the part of the data you will analyze, ., use as the basis of your model. ? Here you specify transformation, scaling, and roles of variables (X or Y or excluded). ? Also, you select the observations (your “ training set” ). ? You can start with the previous workset (Workset / New as model xx) and then modify it, ., excluding observations. ? Whatever you do in Workset does NOT touch the raw data ? Note that outliers are just specified as “ not included” in the next workset (the “ polished” data). Outliers are NEVER removed from the raw data set. Workset: two Modes, Simple and Advanced 4. Analysis Fit the Model to the Workset Data ? Either menu “ Analysis / Autofit” or Fast Button ? A model with appropriate number of ponents is found – If nothing happens, get the two first ponents (also menu or fast button) ? A table appears showing the model, ponent by ponent. ? More ponents can be added (menu or fast button) ? Double click on a model to specify a title 5. Plot results Analysis / menu (or fast buttons) ? Summary / X/YOverview shows R2 and Q2 for all ? Scores – scatter plot, t1t2 and t1u1 amp。 Work set = working copy of data 1 . S t a r t a p r o j e c tF i l e N e wR e a d D a t a F i l eS p e c i f y L a b
