Argument Category Description
InitStateModelColumn Required The name of the model attribute column in the InitStateProb table.
InitStateColumn Required The name of the state attribute column in the InitStateProb table.
InitStateProbColumn Required The name of the initial probability column in the InitStateProb table.
TransAttributeColumn Required The name of the model attribute column in the TransProb table.
TransFromStateColumn Required The name of the source of the state transition column in the TransProb table.
TransToStateColumn Required The name of the target of the state transition column in the TransProb table.
TransProbColumn Required The name of the state transition probability column in the TransProb table.
EmitModelColumn Required The name of the model attribute column in the EmissionProb table.
EmitStateColumn Required The name of the state attribute in the EmissionProb table.
EmitObsColumn Required The name of the observation attribute column in the EmissionProb table.
EmitProbColumn Required The name of the emission probability in the EmissionProb table.
ModelColumn Required The name of the column that contains the model attribute. If you specify this argument, then model_attribute must match a model_key in the PARTITION BY clause.
SeqColumn Required The name of the column that contains the sequence attribute. The sequence_attribute must be a sequence attribute in the PARTITION BY clause.
ObsColumn Required The name of the column that contains the observed symbols.
Observed symbols are case-sensitive.
Incremental Optional Specifies whether only new sequence probabilities are computed: If 'true' (the default), only new sequence probabilities are computed; if 'false', all probabilities are computed.
If the SeqProbColumn argument is omitted, the function cannot determine whether the observed sequence is new; therefore, it treats all model sequences in the input tables as new.
ShowChangeRate Optional If 'true' (the default), the function shows the percentage change that corresponds to the applied model with the difference from previous predicted probability.
SeqProbColumn Optional The function uses the previous value under the column to calculate the change rate.
SkipColumn Optional The name of the column whose values determine whether the function skips the row. The function skips the row if the value is “true”, “yes”, “y”, or “1”. The function does not skip the row if the value is “false”, “f”, “no”, “n”, “0”, or NULL.
Accumulate Optional Specifies the names of the columns in input_table that the function copies to the output table.
