Claim One:
1. A method of analyzing accuracy of linear sensor output based on a theoretical prediction of the output model, the method comprising: analyzing a statistically significant number of linear sensors to obtain a first operating profile for each sensor at a first operating condition, T 1 ; analyzing the statistically significant number of linear sensors to obtain a second operating profile for each sensor at a second operating condition, T 2 ; optionally confirming that each operating profile obtained represents a linear relationship between sensor input and sensor output using reciprocal slopes of output-input lines; optionally confirming that operating profiles developed over a continuum of operating conditions represent a linear relationship using reciprocal slopes of each operating profile; individually testing a linear sensor to obtain at least four data points, wherein the four data points correspond to test data obtained based on a first and second input at each of the first and second operating conditions and are represented as follows: (I 11 , O 11 ), (I 21 , O 21 ), (I 12 , O 12 ), and (I 22 , O 22 ); developing a theoretical prediction of the output model from the four data points, wherein the theoretical prediction of the output model for determining output at a given operating condition, T, and based on a given input, I, is developed in accordance with the following mathematical equation: 
 Output= O 0 +I/b, wherein b=b 1 +[(b 1 −b 2 )/(T 1 −T 2 )](T−T 1 ), where b 1 =(I 11 −I 21 )/(O 11 −O 21 ); b 2 =(I 12 −I 22 )/(O 12 −O 22 ); and O 0 =(O 01 +O 02 )/2, where O 01 =O 11 −I 11 /b 1 and O 02 =O 12 −I 12 /b 2 ; comparing accuracy of the relationship between the theoretical prediction of the output model for the first operating condition to sensor output in the first operating profile for the first operating condition corresponding to the given input; and comparing accuracy of the relationship between the theoretical prediction of the output model for the second operating condition to sensor output in the second operating profile for the second operating condition corresponding to the given input.
