Weighted update of sufficient statistics (Bayes rule). | |
void | bayes (const vec &dt) |
Incremental Bayes rule. | |

Protected Attributes | |
double | frg |
forgetting factor | |
double | last_lognc |
cached value of lognc() in the previous step (used in evaluation of ll ) | |
RV | drv |
Random variable of the data (optional). | |
double | ll |
Logarithm of marginalized data likelihood. | |
bool | evalll |
If true, the filter will compute likelihood of the data record and store it in ll . Set to false if you want to save computational time. | |
Extension to conditional BM | |
This extension is useful e.g. in Marginalized Particle Filter (bdm::MPF). Alternatively, it can be used for automated connection to DS when the condition is observed | |
const RV & | _rvc () const |
access function | |
virtual void | condition (const vec &val) |
Substitute val for rvc . | |
RV | rvc |
Name of extension variable. | |
Logging of results | |
void | set_options (const string &opt) |

void | log_add (logger *L, const string &name="") |

void | logit (logger *L) |
ivec | LIDs |
IDs of storages in loggers. | |
bool | opt_L_bounds |
Option for logging bounds. |
