Hello,

I hope someone here could explain to me in detail about this statement (got it from AAA help file).

'The regression coefficients, A and B, are calculated from existing airplane data. The user should input about 30 similar researched planes with take-off and empty weights ranging over a factor of 10. A linear regression is then performed utilizing a least squares fit to solve for A and B'

What does the word 'ranging over a factor of 10' means?

Thanks. Smile
