29 lip 2015 · The easy way of course would be simply to calculate the analytic derivative and write a function to produce it. This will calculate and plot it using the gradient function. Experiment with it to get the result you want: Theme. Copy. DF = openfig ('AB ABOULOUARD fig.fig'); H1 = get (gca, 'Children'); % Get Handle To Data In ‘.fig’ File.
Is there some simple way of calculating of p-value of t-Test in MATLAB. I found something like it however I think that it does not return correct values: Pval=2*(1-tcdf(abs(t),n-2)) I want to calculate the p-value for the test that the slope of regression is equal to 0. Therefore I calculate the Standard Error.

26 kwi 2023 · Fatigue damage accumulation for variable amplitude stress-time histories using the Palmgren-Miner rule coded in Matlab. Code is documented and easy to use. The design fatigue strength curve (S-N or stress-life curve) is specified using the standardized parameters from Eurocode 3 EN 1993-1-9.
9 cze 2016 · I would like to find out if the slope of these two lines are different, using some sort of statistical test. I can calculate the slope of each with: lm = fitlm(d(:,1),d(:,2),'linear'); lm2 = fitlm(d(:,1),d(:,3),'linear'); whch shows that, lm: Estimated Coefficients: Estimate SE tStat pValue.
18 sie 2015 · I have a data A,B and I want to calculate the slope between two existing points I want to find the slop between 2012 & 2013 points I try: A=[ 234228; 249150 ; 265021 ;281904 ;299862 ];
y = β 0 + β 1 x + ϵ, where β 0 is the y-intercept, β 1 is the slope (or regression coefficient), and ϵ is the error term. Start with a set of n observed values of x and y given by (x 1, y 1), (x 2, y 2), ..., (x n, y n). Using the simple linear regression relation, these values form a system of linear equations.
