Hello,
I fit my data to gamma distribution using the gamfit function of MATLAB.
The gamfit function returns MLEs and 95% percent confidence intervals as follows:
a = 2; b = 4;data = gamrnd(a,b,100,1);
[p,ci] = gamfit(data)
p =
2.1990 3.7426
ci =
1.6840 2.8298
2.7141 4.6554
I am interested in finding the standard error of the coefficients rather than the confidence interval.
I want to know how to compute the standard errors based on the confidence interval??
Moreover, likelihood ratio hypothesis test were used to test hypotheses such as p(1)=0.5, but I dont know how to obtaine and input the NullLLF and BaseLLF values
Syntax likelihood ratio hypothesis test
[H,pValue,Ratio,CriticalValue]=lratiotest(BaseLLF,NullLLF,DoF,Alpha)
