x
[ tseries ] - Input time series that will be normalised.
NormDate
[ numeric | 'start'
| 'end'
| 'nanStart'
| 'nanEnd'
] - Date relative to which the input data will be normalised; if not specified, 'nanStart'
(the first date for which all columns have an observation) will be used.
X
[ tseries ] - Normalised time series.'mode='
[ 'add'
