WebFeb 18, 2024 · Accepted Answer: Jeff Miller I'm trying to fit beta distribution parameters to a [1X60] size vector (provided below as x) using betafit () funciton but the obtained parameters do not make sense (alpha=0.3840 beta= 23.4999), presenting a distribution which is far from representing the data. WebOct 22, 2024 · The Beta distribution has an extremely flexible shape, much more versatile than the normal distribution. Its default support or domain is the interval [0;1] for its random variates of x. Below, we will see how the support can be extended to much wider intervals by adding location and scale parameters to the two share parameters.
