| Jul 5, 2023 at 18:25 | comment | added | Joel | Apologies for not doing so initially-first question so learning how best to format questions here. From what I understand the definition of type 3 SS is universal so I would expect them to be equivalent. The difference seems to be that different software packages (or coding environments) seem to prefer type 2 or type 3 SS. Type 1 SS seems to be used less often as it emphasizes the factor(s) listed first (hence the order of the factors changes the result. | |
| Jul 5, 2023 at 18:21 | comment | added | JimB | Thanks for adding that. For whatever it's worth, those values for XLSTAT and Graphpad Prism match what SAS gives. | |
| Jul 5, 2023 at 18:20 | comment | added | Joel | Thank you both for your responses. I have updated my question to include outputs from both XLSTAT and Graphpad Prism for the type 3 SS. I will look into LinearModelFit to see if the output is equivalent to that of XLSTAT. | |

Because not all software uses the same definition of Type III SS, please give the results from XLSTAT or SAS or R that you want from the data and model you provided. As @BenIzd mentions LinearModelFit gives an option for obtaining PartialSumOfSquares which is what Type III SS are sometimes called. However, this doesn't match what SAS gives for Type III SS.

Welcome to the community. FittedModel (produced by LinearModelFit) have a property called "SequentialSumOfSquares", and "PartialSumOfSquares" which is what you're looking for (based on my limited knowledge, it doesn't support All, and other statistics should be calculated manually).
