Is it possible to find the sum of squared error of a simple linear regression on fx-991EX?

You have 2 possibilities

1. Calculate regression in Statistics mode, recall variables (see the page 21 of the UG) and use them for manual calculation of the SSE - see the formula on the pages 14.9, 14.18 and 14.19 

2. Calculate the complete regression and the SSE manually in spreadsheet mode - see the formulas on the pages 14.9, 14.11 and 14.19, except these formulas you need to compute all variables to determine b0, b1 and SSE - n, sum x^2, sum xy, average x, average y, (average x)^2, sum y^2, sum y, 

A nice tutorial with formulas and exercises, pages 14-9 to 14.19
