clarification required

Dear Friends,
I am not clear about the difference in Analogous estimating & Parametric Estimating.
As per my knowledge, both of them use historical information to estimate, so what is the difference ?
Kindly help me in understanding this.
Regards
Hari

Analogous is saying that
Analogous is saying that because his house took $X my house will also take around $X . . Here house completed earlier provides the data of cost. Hence it uses historical information. Parametric is saying that because his house is 1000 Sq ft and it took $X to complete my house being 2000 sq ft with same quality it will take $2X ... here you can see some extrapolation.
