WebTo get more technical: - An F distribution is the ratio of two Chi-square variables, each of which is divided its respective degrees of freedom. So (C1/c1) / (C2/c2), where the capital letters are the random variable (RV), and the lowercase are the degrees of freedom. - A t-distribution is the ratio of a Standard Normal divided by the square ... WebThis won't tell you if the distribution fits or not, so you must then use goodness of fit test. For this, you can use ks.test: require (vcd) require (MASS) # data generation ex <- rexp (10000, rate = 1.85) # generate some exponential distribution control <- abs (rnorm (10000)) # generate some other distribution # estimate the parameters fit1 ...
