confint and predint bounds trouble. Learn more about confint, bounds, statistics MATLAB. confint is a generic function. The default method assumes normality, and needs suitable coef and vcov methods to be available. The default method can be called directly for comparison with other methods. For objects of class "lm" the direct formulae based on t values are used. ci = confint (fitresult,level) returns confidence bounds at the confidence level specified by level. level must be between 0 and 1. The default value of level is 0.95. Examples collapse all Obtain the Confidence Intervals for Fit Coefficients Using the confint Function Load the data and call the fit function to obtain the fitresult information.

Web. Tom Lane on 31 May 2012 1 Link Translate CONFINT returns confidence intervals for the parameters. So if you fit y=a+b*x, you get confidence intervals for a and b. PREDINT returns confidence intervals for predicted values. So if you supply x values x1,x2,x3, you get confidence intervals for the three quantities a+b*x1, a+b*x2, and a+b*x3. cf_coeff = coeffvalues (cf); cf_confint = confint (cf); a = cf_coeff (1); b = cf_coeff (2); a_uncert = (cf_confint (2,1) - cf_confint (1,1))/2; b_uncert = (cf_confint (2,2) - cf_confint (1,2))/2; One note of caution: The errors of a and b will generally be correlated, which makes them unnecessarily big.

Jan 30, 2015 at 8:31 If you want a 95% CI, you just have to use the function like ci = confint (fitresult,0.95). Niko, where did you get this formula? - A. Donda Jan 31, 2015 at 18:18 Add a comment 1 Answer Sorted by: 2 Yep. Get all the output parameters of lsqcurvefit and use them in nlparci like so:. CONFINT returns confidence intervals for the parameters. So if you fit y=a+b*x, you get confidence intervals for a and b. PREDINT returns confidence intervals for predicted values. So if you supply x values x1,x2,x3, you get confidence intervals for the three quantities a+b*x1, a+b*x2, and a+b*x3. Web. Web. Web. Web. Web. However, one simple solution is to allow the toolbox to treat A, w, and p as "coefficients", as follows: f = fittype ('A*cos (w*x + p)','coefficients', {'A', 'w', 'p'}); In this case, the code will not throw an error, and will return 95% confidence intervals on A, w, and p. I hope that helps. cjh 856 Similar question. 1 CONFINT returns confidence intervals for the parameters. So if you fit y=a+b*x, you get confidence intervals for a and b.
