MOVAVG {bimets} R Documentation

## Moving Average

### Description

This function returns the moving average of the elements of the input array or the input time series. The result is an object of the same class of the input, and its elements are the moving average of length `L` of the input values. If the input is a time series, the `DIRECTION` of the moving average, i.e backward, forward or centered, can be provided. `MAVE` is an alias for `MOVAVG`

### Usage

```MOVAVG(x = NULL, L = NULL, DIRECTION = NULL, avoidCompliance = FALSE, ...)
MAVE(x = NULL, L = NULL, DIRECTION = NULL, avoidCompliance = FALSE, ...)
```

### Arguments

 `x` Input numerical array or time series that must satisfy the compliance control check defined in `is.bimets`. `L` Length of the mean. Must be a positive integer. `DIRECTION` if `x` is a time series, given `y` as output and `x` as input: AHEAD: the output observation value in index `n` will be `y[n] = mean(x[n],x[n+1],...,x[n+L-1])`. CENTER: the output observation value in index `n` will be `y[n] = mean(x[n-trunc(L/2)],...,x[n],x[n+1],...,x[n+trunc(L/2)])`. NULL o BACK: (default) the output observation value in index `n` will be `y[n] = mean(x[n+1-L],...,x[n-1],x[n])`. `avoidCompliance` If `TRUE`, compliance control check of input time series will be skipped. See `is.bimets` `...` Backward compatibility.

### Value

This function returns an object of the same class of the input, i.e. an array or a BIMETS time series.

`TSDELTA`
`TSLAG`
`TSPROJECT`
`TSEXTEND`
`TSLEAD`
`CUMSUM`
`INDEXNUM`

### Examples

```
#input data
inputArray=c(1,2,3,4,NA,1,2,3,4,5)

#array lag 3
out_movavg=MOVAVG(inputArray,3)
print(out_movavg)

#ts lag 4 centered with missings
ts1=TSERIES(inputArray,START=c(2000,1),FREQ='A')
out_movavg=MAVE(ts1,4,'CENTER')
TABIT(out_movavg)

#ts daily
ts1=TSERIES(inputArray,START=c(2000,1),FREQ='D')
out_movavg=MAVE(ts1,3)
TABIT(ts1,out_movavg)

```
