    Intercept and scale in the picture correspond to Weibull double parameters， right? Intercept means shape parameters in Weibull function, and scale means shape parameters, right? Thank you ... View more

I need to limit a parameter in Weibull to a fixed value, make theta = 5, and mixed FMM. As you said, subtraction can not achieve the purpose. My code is as follows. Where is the error code? I use the restrict code，thank you data all; input plot spcs $ D; cards; 1 b 25.3 1 b 18 1 l 8.8 1 l 11.9 1 l 9.8 (Omit most data) run; proc fmm data=all plots=density; model d = / dist=weibull link=log k=2 parms; restrict theta=5 ; run;   ...

I want to fit FMM with two three parameter Weibull, and set the position parameter to a fixed value theta = 5. There is a problem with the display code after input. Thank you for pointing out the error for me. Thank you！ proc fmm data=all plots=density; model d = / dist=weibull( theta=5) link=log k=2; run;   ... View more

thank you ! Is theta means location parameter？ ... View more

On this basis, what code do I use to turn two parameters into three parameters? And I want to set the parameter a to the fixed value a = 5， and only ask for the values of B and C. what changes do I need to make in my code? thank you ... View more

Hello, I want to ask a question. . It is not known whether the SAS FMM program can match two three parameter Weibull distributions. If so, what code can I use? Thank you. ... View more
