Maximum likelihood estimators for gamma distribution

WebThe gamma distribution takes values on the positive real line. Special cases of the gamma are the exponential distribution and the chi-square distributions. Applications of the … WebDescription phat = gamfit (data) returns the maximum likelihood estimates (MLEs) for the parameters of the gamma distribution given the data in vector data. [phat,pci] = gamfit (data) returns MLEs and 95% percent confidence intervals. The first row of pci is the lower bound of the confidence intervals; the last row is the upper bound. Web19 apr. 2024 · Machine learning is a huge domain that strives hard continuously to make great things out of the largely available data. With data in hand, a machine learning algorithm tries to find the pattern or the distribution of that data. Machine learning algorithms are usually defined and derived in a pattern-specific or a distribution-specific manner. states with health exchanges
