| Post subject: | How does lsfitcreatewf utilize the weighting values? |
For non-linear regression functions such as lsfitcreatewf how are the weighting values applied. I'm fitting a 4 parameter logistics value and need to provide for 1/y and 1/y^2 weighting. Are these values used for weighting on minimizing the sum of squares (which is what I want) or is it used in some other fashion? |
