on re-arrangement (temp in deg C)
In this case temperature and frequency are independent variables and humidity is dependent on both of them. Humidity seems directly proportional to frequency if analyzed for humidity Vs Frequency and temperature seems inversely proportional to frequency while analyzed Temp Vs Frequency.
I need to be able to make an equation which gives Humidity upon solving with known temperature and frequency. For example if I input F = 8179 and T = 20.5, H should be near to 42%.
interp2 from MATLAB for frequency vs humidity and got much errors and tried least square method manually but ended getting nothing near. Specifically I do not have idea on modeling for 3 Variable equation. What may be the way for modeling 3 variable equations upon this small sets of data. Thanks.
