In the same way, select the variables X11 and X21 in the Explanatory field. Select the variable Y and click on the OK button. Once the data file is imported, click into the first data field of the dialog box in order to select the Dependent variable:Ī new window pops up listing the imported variables. Running a linear regression on a large data file To see a preview before loading the data file, click on the Preview button:

an element with space, delimiter character, etc), c) the Start import at row field allowing to skip the firsts lines used as header (here, none are skipped) and d) the Comment qualifier field necessary for commented text in the file (here, for each line, all text after the character “#” isn’t loaded).

A question mark appears then automatically next to the first data field. To use a text file as data source, click on the mouse icon until the orange paper sheet appears. The Linear Regression dialog box then appears.

Once XLSTAT is open, select the XLSTAT / Modeling data / Regression function. Therefore, we are able to load data files which exceed the standard Excel worksheet size (1,048,576 rows by 16,384 columns in Excel 2016).

XLSTAT allows loading data into the computer’s memory rather than the worksheet. Setting up the import of a large data file with XLSTAT The goal of this tutorial is to show a) how to import a large txt file into Excel using the Import data tool of XLSTAT and b) how to run a linear regression on the imported data.

The file contains only a very limited number of observations but you can repeat the below procedure using txt or cvs files containing millions of rows. Datasetĭata are fictitious and were created for this tutorial. This tutorial explains how to set up and run a linear regression on large data files into Excel using the XLSTAT software.
