Benchmarking by means of the Cholette method.
cholette( s, t, rho = 1, lambda = 1, bias = "None", conversion = "Sum", obsposition = 1 )cholette( s, t, rho = 1, lambda = 1, bias = "None", conversion = "Sum", obsposition = 1 )
s |

t |
Aggregation constraint. Mandatory |
obsposition |

Cubic splines are piecewise cubic functions that are linked together in a way to guarantee smoothness at data points. Additivity constraints are added for benchmarking purpose and sub-period estimates are derived from each spline. When a sub-period indicator (or disaggregated series) is used, cubic splines are no longer drawn based on the low frequency data but the Benchmark-to-Indicator (BI ratio) is the one being smoothed. Sub- period estimates are then simply the product between the smoothed high frequency BI ratio and the indicator.
cubicspline( s = NULL, t, nfreq = 4, conversion = c("Sum", "Average", "Last", "First", "UserDefined"), obsposition = 1 )cubicspline( s = NULL, t, nfreq = 4, conversion = c("Sum", "Average", "Last", "First", "UserDefined"), obsposition = 1 )
s |
Disaggregated series. If not NULL, it must be the same class as t. |
t |
Aggregation constraint. Mandatory. it must be either an object of class ts or a numeric vector. |
nfreq |

conversion |
Conversion rule. Usually "Sum" or "Average". Sum by default. |
obsposition |
Postion of the observation in the aggregated period (only used with "UserDefined" conversion) |

Denton method relies on the principle of movement preservation. There exist a few variants corresponding to different definitions of movement preservation: additive first difference (AFD), proportional first difference (PFD), additive second difference (ASD), proportional second difference (PSD), etc. The default and most widely adopted is the Denton PFD method.
denton( s = NULL, t, d = 1, mul = TRUE, nfreq = 4, modified = TRUE, conversion = c("Sum", "Average", "Last", "First", "UserDefined"), obsposition = 1 )denton( s = NULL, t, d = 1, mul = TRUE, nfreq = 4, modified = TRUE, conversion = c("Sum", "Average", "Last", "First", "UserDefined"), obsposition = 1 )

t |
Aggregation constraint. Mandatory. it must be either an object of class ts or a numeric vector. |
d |

nfreq |

Denton proportional method can be expressed as a statistical model in a State space representation (see documentation for the definition of states). This approach is interesting as it allows more flexibility in the model such as the inclusion of outliers (level shift in the Benchmark to Indicator ratio) that could otherwise induce unintended wave effects with standard Denton method. Outliers and their intensity are defined by changing the value of the 'innovation variances'.

temporaldisaggregationI( series, indicator, conversion = c("Sum", "Average", "Last", "First", "UserDefined"), conversion.obsposition = 1, rho = 0, rho.fixed = FALSE, rho.truncated = 0 )temporaldisaggregationI( series, indicator, conversion = c("Sum", "Average", "Last", "First", "UserDefined"), conversion.obsposition = 1, rho = 0, rho.fixed = FALSE, rho.truncated = 0 )
series |
The time series that will be disaggregated. It must be a ts object. |
indicator |
High-frequency indicator used in the temporal disaggregation. It must be a ts object. |
conversion |
Conversion mode (Usually "Sum" or "Average") |
conversion.obsposition |
Only used with "UserDefined" mode. Position of the observed indicator in the aggregated periods (for instance 7th month of the year) |
rho |
Only used with Ar1/RwAr1 models. (Initial) value of the parameter |
rho.fixed |
Fixed rho (T/F, F by default) |
rho.truncated |
Range for Rho evaluation (in [rho.truncated, 1[) |
