Detailed Description

Parameters and results from least squares fit with errors in both co-ordinates.

Mascot Parser does not contain the code to calculate the fit. This class just returns the result of the fitting of a straight line: y = a + bx

The results are stored in XML in a "fitexy" entity.

Member Function Documentation

double getA

(

)

const

Get the a value.

The fitted line is y = a + bx

Returns:

The a value.

double getB

(

)

const

Get the b value.

The fitted line is y = a + bx

Returns:

The b value.

double getChi2

(

)

const

Get the chi-squared value.

Returns:

The chi-squared value.

double getQ

(

)

const

Get the chi squared probabilty. The larger the value, the better the fit.

The goodness of fit probability q that the fit would have getChi2() this large or larger

Returns:

The Q value.

double getSigmaA

(

)

const

Get the a sigma.

The relative probable uncertanty of 'a'

Returns:

The a sigma.

double getSigmaB

(

)

const

Get the b sigma.

The relative probable uncertanty of 'b'

Returns:

The b sigma.

double getSigmaX

(

)

const

Get the x sigma.

Returns:

The x sigma.

double getSigmaY

(

)

const

Get the y sigma.

The standard deviation of y data.

Returns:

The y sigma.
