Here I have a group of data which following the Gamma distribution and now I want to use Naive Bayes method to fit this data. I tried the original function named ‘fitcnb’ and knowing that it providing 4 types of distribution: ‘box’, ‘epanechnikov’, ‘normal’ and ‘triangle’. Now I want to…

Hi everyone, I am not sure if I apply the T-Test correctly to my data. In the description it says “H = TTEST(X) performs a t-test of the hypothesis that the data in the vector X come from a distribution with mean zero, and returns the result of the test…

I need to read german text from a file and translate it into ascii-numbers. Of course it contains german umlauts ‘ä’, ‘ö’, ‘ü’ and the character ‘ß’ as well. After using fscanf my resulting string contains only the ‘?’, where these chars were. Changing the encoding in Matlab doesn’t work…

Say I have a very complicated probability distribution function: x^(-2)*y^(-3)*exp(-z/t), where x y z t are all continuous positive numbers. The integration in x,y,z,t space is not 1, so there has to be some scaling factor. How can I devise a function, or is there a convenient function with some…

I applied my code to data simplenarx_dataset. To do this I performed the following steps: 1 — I have done autocorrelation and cross correlation peaks to see that gives us more information. ID = 1, FD = 1 2 — I have found H, where H = 5 3 —…

Hi I ran a hyperparameter optimization to find the best parameters for a two-class classification problem using fitcensemble. But when I try to use these I get a strange warning: Warning: You must pass ‘SplitCriterion’ as a character vector ‘mse’ for regression. What is wrong with my code? The warning…

I have an object of which there is a symmetrical pattern, i want to plot a line of symmetry and then determine the array co-ordinates of the boundary point of the that line of symmetry. For example consider below: How could i go about detecting the line of symmetry for…

Hi, I’d like to find the inflection points of this noisy signal. Do you have any suggestions on how to do this? fs = 100; %Hz dt = 1 / fs; t = 0:dt:2; x = sin(3 * pi * t) - (3 * cos(11 * pi * t)); x_noise = x + (1.5…
