I'm trying to calculate the 95% confidence intervals based off a series of matrices based in Matlab: I know how to calculate the required sensitivity, specificity, negative predictive value and positive predictive value, however I'm not sure, given these data, how to calculate the 95% confidence interval. Any help would be greatly appreciated.

At the moment I just plot the pxxc confidence interval array obtained when calling it in the pwelch function, and its looks very confusing (a lot of noise!). confidence interval coxphfit hazard ratio MATLAB Hi everybody. I am using coxphfit to compute P-values and hazard ratios for data related to clinical trials and need to be able to compute a the 2-sided 95% confidence interval of the hazard ratio. With so few data points and if you don't know if the distribution is normal I would look into using bootstrap confidence interval. It's a non-parametric method so you are not assuming normality. The MATLAB function bootci implements this method. Here is the documentation for bootci.

Also, it is termed a 95% confidence interval, not 5% . I mention this to avoid confusion.

When you fail your goals. A 95% confidence level does not mean that 95% of the sample data lie within the confidence interval.

The confidence interval is defined as ybar +- T_multiplier*std/sqrt(n). the tinv command provides the T_multiplier ci = 0.95;

I want to draw a plot in Matlab or Stata. I have a mean and CI for some distribution. there should be a line with the upper end of the line representing the upper CI and the lower end the lower CI and the middle, the average. I am not sure how to do it or how to search for it.

To demonstrate, the 95% confidence interval of your paramter estimate (using nlparci) is CI = [0.035 0.052] which means the k_opt parameter may vary between [0.035 0.052] within the interval. The plot below shows a range of possible curves when the k_opt parameter is varied between those bounds.
