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.

I have fit some data in the curve fitting toolbox in Matlab using a fit comprised of 2 summed Gaussians. Matlab was able to plot the upper and lower 95% confidence intervals for me very nicely.

Table 3 and Table 4 Denna matris används i programvaran Matlab för att räkna ut obalansen för ett stort spridningen är stor anges det ett interval. Skillnaden mellan 95-% och 100-% värden av obalans kommer confidence between zero and four.

I'm not sure what you meant by confidence intervals graph, but this is an example of how to plot a two-sided 95% CI of a normal distribution: After reading numerous threads, here's my attempt. % Get some random data x = linspace (0.3, pi-0.3, 10); Data = sin (x) + randn (1, 10)/10; Data_sd = 0.1+randn (1,10)/30; % prepare it for the fill function x_ax = 1:10; X_plot = [x_ax, fliplr (x_ax)]; Y_plot = [Data-1.96.*Data_sd, fliplr (Data+1.96.*Data_sd)]; % plot a line + confidence For example, if you construct a confidence interval with a 95% confidence level, you are confident that 95 out of 100 times the estimate will fall between the upper and lower values specified by the confidence interval.

Hi Sara, To calculate the 95% confidence intervals of your signal, you first will need to calculate the mean and *|std| (standard deviation) of your experiments at each value of your independent variable. The standard way to do this is to calculate the standard error of the mean at each value of your independent variable, multiply it by the Significance level for the confidence interval, specified as the comma-separated pair consisting of 'Alpha' and a scalar value in the range (0,1). The confidence level of ci is 100 (1–Alpha) %. The default value 0.05 corresponds to a 95% confidence interval.

I can easy calculate the mean but now I want the 95% confidence interval. I can calculate the 95% confidence interval as follows: CI = mean (x)+- t * (s / square (n)) where s is the standard deviation and n the sample size (= 100).

[Y,DELTA] = polyconf(p,X,S) takes outputs p and S from polyfit and generates 95% prediction intervals Y ± DELTA for new observations at the values in X. This MATLAB function computes 95% confidence intervals for the estimated parameters from fitResults, an NLINResults object or OptimResults object returned by the sbiofit function. it'll automatically show the 95% confidence interval, so it shoud be: wt( your time series data) you can also use wtc(v1,v2) to show the coupling btw two variables. i have a signal so it's just data, that i load on Matlab and I have to plot 95% confidence interval according to student t-distribution of my signal. Exactly like photo, that i added.
