Detailed Description

class for performing Linear Fitting with Origin's internal fitting engine

Member Function Documentation

fix_intercept()

originpro.analysis.LinearFit.fix_intercept	(		self,
			val )

fix intercept to a value
Parameters:
    val(float): intercept value
Returns:
    none
Examples:
    lr=op.LinearFit()
    lr.fix_intercept=0.6

fix_slope()

originpro.analysis.LinearFit.fix_slope	(		self,
			val )

fix slope to a value
Parameters:
    val(float): slope value
Returns:
    none
Examples:
    lr=op.LinearFit()
    lr.fix_slope=0.6

report()

originpro.analysis.LinearFit.report	(		self,
			band = 0 )

perform the fitting and generate the report. You need to end the fitting by either calling result or report

Parameters:
    band (int): confidence and prediction bands. 0=none,1=confidence,2=prediction,3=both

Returns:
    (tuple): range strings of the report sheet and the fitted curves

Examples:
    lr = op.LinearFit()
    lr.set_data(wks, 1, 2)
    r, c = lr.report(1)
    wReport=op.find_sheet('w', r)
    wCurves=op.find_sheet('w', c)

result()

originpro.analysis.LinearFit.result

(

self

)

perform the fitting and return the parameters. You need to end the fitting by either calling result or report

Return:
    (dict) fitting parameters and statistics from the fit

Examples:
    lr = op.LinearFit()
    lr.set_data(wks, 1, 2)
    rr = lr.result()
    b       =rr['Parameters']['Slope']['Value']
    b_err   =rr['Parameters']['Slope']['Error']

set_data()

originpro.analysis.LinearFit.set_data	(		self,
			wks,
			x,
			y,
			err = '' )

set the XY data with optional error bar column
Parameters:
    wks(worksheet):
    x,y(int or string):column index or name
    err(int or string):column index or name
Returns:
    none
Examples:
    lr = op.LinearFit()
    wks=op.find_sheet()
    lr.set_data(wks, 1, 2)
