This "spreadflow" was created by searching Seekda for a statistics webservice, adding it using "Web Services References" in Excel, and creating a simple VBA module to implement the corresponding Excel functions (sum, average, standard deviation etc) . The module simply gathers data from the cells to build an array of doubles that can be passed to the webservice. For more details about adding webservices to Excel see the inchidemo workflow http://www.myexperiment.org/workf...
