Question: Fitting constants to equation

Hi guys,

I am trying to fit some constants to an equation in maple but am very new to the software and am struggling somewhat to input he correct commands.

I have the following equation;

x=a(y^b)(z^c)

And I have data points for x, y and z

I need to calculate the best fit value for a, b and c based on this data.

These constants are material properties for calculating creep in a structures and the data is somewhat dirty, therefore my hand calcs lead to an unsolvable results so best fit values are my only hope!

Any suggestions or a nudge in the right direction would be wonderful!

Thanks 

Steve
