Command:
addFacGamma ( |
|
What:
Adds a new factor with a Gamma distribution to the configuration to be used for the sample generation
Parameters:
name [char*] |
defines
the factor's name. It must begin with a letter and can contain only
letters and numbers, this parameter cannot be null! |
r [double precision #] |
r parameter of the distribution |
lambda [double precision #] |
lambda parameter of
the distribution |
b [double precision #] |
b parameter of the distribution |
trunc [double precision #] |
right truncation value for the distribution |
note [char*] |
the
factor note is optional in Matlab |
Return:
error_code [int]: 1 if the operation has occurred without errors, 0 if an error has occurred
Examples:
addFacGamma('fac1', 1, 1, 0, 0.999, 'fac1note')
this command creates a new factor called fac1 with a gamma distribution which parameters r, lambda and b values respectively are 1, 1 and 0 while the distribution is truncated after 0.999
About the
distribution:
The density function of
the Gamma distribution has the following expression:
with with r>0 , λ>0 , b≥0 and x≥b
mean value: standard deviation:
