EMGsim {dynr} R Documentation

## Simulated single-subject time series to capture features of facial electromyography data

### Description

A dataset simulated using an autoregressive model of order (AR(1)) with regime-specific AR weight, intercept, and slope for a covariate. This model is a special case of Model 1 in Yang and Chow (2010) in which the moving average coefficient is set to zero.

### Usage

data(EMGsim)


### Format

A data frame with 500 rows and 6 variables

### Details

The variables are as follows:

• id. ID of the participant (= 1 in this case, over 500 time points)

• EMG. Hypothetical observed facial electromyograhy data

• self. Covariate - the individual's concurrent self-reports

• truestate. The true score of the individual's EMG at each time point

• trueregime. The true underlying regime for the individual at each time point
