Instruction for csQCA

Preparation

To use the Add-In, open the Excel file available here. The Add-In comes with a digital signature issued to Lasse Cronqvist. Please check this signature in Excel (sadly, signatures are not shown on MacOS). If you are requested to confirm the use of the document, do so.

Then, to perform a simple csQCA calculation, select the QCA menu in the menu bar. The QCA menu should be placed at the right side in the menu bar.

Select data

Select the data to be included in the analysis in the data file. The data can be placed anywhere in the data sheet, but the name of the conditions and the outcome must be found in the first row and this row must be selected as well.

Perform the csQCA

Select the csQCA item in the QCA menu.

If the data selected is a valid data set for QCA analysis, the QCA Window will appear.

In this window, select the case ID, outcome and conditions by selecting their names in the variables detected list and click the appropriate button.
 
Then select the outcome value (0 or 1) for the csQCA. Enable the checkbox Include Logical Remainders if you want to include the logical remainders in the analysis.
 
If QCA Notation is checked, the prime implicants and the solutions for csQCA data sets will be shown using a upper-/lower-case notation. Else, set notation will be used (e.g. A{0}*B{1} in set notation equals a*B in upper-/lower-case notation).
 
Press do calculations and the results will be shown in a new worksheet named QCA Result.
 
You can respecify your calculations in the QCA dialogue box. To switch back to the data, you have to close the dialogue box first.
