It depends on what kind of "linear regression" are you interested in. For instance:

1. Just linear regression, as in y=a*x+b, or you'd also want power (y=a*x^b), logarithmic (y=a+b*ln(x)), etc ... fits ?
2. Just linear regression in one variable, as in y=a*x+b, or you'd also want linear regression for multiple variables: y=a0+a1*x1+a2*x2+a3*x3+...+an*xn ?
3. Just linear regression of degree 1, as in y=a*x+b, or polynomial regression of degree n: y=a0+a1*x+a2*x^2+...an*x^n ?
   

There are many possibilities with various degrees of complexity, you see.
