Public Member Functions | |
| void | from_setting (const Setting &set) |
| virtual string | to_string () |
| This method returns a basic info about the current instance. | |
| virtual void | to_setting (Setting &set) const |
| This method save all the instance properties into the Setting structure. | |
| virtual void | validate () |
| This method TODO. | |
Constructors | |
| mpdf () | |
| mpdf (const mpdf &m) | |
copy constructor does not set pointer ep - has to be done in offsprings! | |
Matematical operations | |
| virtual vec | samplecond (const vec &cond) |
Returns a sample from the density conditioned on cond, . | |
| virtual mat | samplecond_m (const vec &cond, int N) |
| Returns. | |
| virtual void | condition (const vec &cond) |
Update ep so that it represents this mpdf conditioned on rvc = cond. | |
| virtual double | evallogcond (const vec &dt, const vec &cond) |
| Shortcut for conditioning and evaluation of the internal epdf. In some cases, this operation can be implemented efficiently. | |
| virtual vec | evallogcond_m (const mat &Dt, const vec &cond) |
| Matrix version of evallogcond. | |
| virtual vec | evallogcond_m (const Array< vec > &Dt, const vec &cond) |
| Array<vec> version of evallogcond. | |

| void bdm::mpdf::from_setting | ( | const Setting & | set | ) | [inline, virtual] |
Load from structure with elements:
{ rv = {class="RV", names=(...),}; // RV describing meaning of random variable
rvc= {class="RV", names=(...),}; // RV describing meaning of random variable in condition
// elements of offsprings
