This R pargram extracts multiple commonly used features for weekday and weekends from minute level actigraphy data. Weekday and weekends could be merged with the holiday days when holidayFN was specified. In GGIR, sleep period was defined from today noon to tomorrow noon in general, so weekends should be Friday and Saturday (wake up in Saturday and Sunday morning). To be noted,  sleeponset in Sunday is counted as normal weekday in default since people need to work on Monday. For physical activity, weekends should be Saturday and Sunday for the purpose to calculate daytime activity.

## 1. Data

The activity data at the minute level (`r enmoFN`) was stored in a format of `data.frame` of dimension $(\sum_i d_i) \times `r ncol(D1)`$, where $d_i$ is the number of available days for subject $i$. And the order of the `r ncol(D1)` columns (and corresponding column names) was as follows, `r colnames(D1)[1:Ctop]`, "MIN1", ..., "MIN1440".  
   
     *  Raw data = (`r dim(D1)`), `r length(unique(D1[,"filename"]))` files, `r length(unique(D1[,"newID"]))` individuals.
     *  Clean data = (`r dim(D2)`), `r length(unique(D2[,"filename"]))` files, `r length(unique(D2[,"newID"]))` individuals.     
     *  Remove daysleepers = (`r dim(D3)`), `r length(unique(D3[,"filename"]))` files, `r length(unique(D3[,"newID"]))` individuals.  
     *  Count data = (`r dim(count)`), `r length(unique(count[,"ID"]))` individuals. 
     *  `r D3.days$holiday.story`     
     *  WD Count data = (`r dim(count.wd)`), `r length(unique(count.wd[,"ID"]))` individuals.  
     *  WE Count data = (`r dim(count.we)`), `r length(unique(count.we[,"ID"]))` individuals.

## 2. Feature Extractions  
* Circadian rhythmicity
    * functional PCA: `fpca.face (refund)` and ` denseFLMM` 
    * extended cosinor model with anti logistic transformed cosine curves: `ExtCos`, `ExtCos_long`
    
  

### 2.4 cosinor model
The classic cosinor model is defined as $r(t)= mes + amp \times c(t)$ where $c(t) = \cos([t-\phi]2\pi/24)$ where mes is mesor, amp is amplitude, $\phi$ is the acrophase. 

```{r text,include=FALSE}
# Extended cosinor model allows for two additional parameters to control the shape. Here we implement the anti logistic transformation, and have $r(t) = min +amp\times F(c(t))$, where $F()$ is the anti logistic function.


# `ExtCos` and `ExtCos_long` calcualte the five parameters, (for a single vector amd whole dataset respectively). It is suggested to log transformed the curve by choose `logtransform = TRUE`. 
```

### 2.6 functional principal component analysis

As opposed to Cosinor/extCosinor model, functional principal component analysis (FPCA) is a data driven technique that makes no parametric assumptions about the functional form of diurnal patterns. FPCA represents any sample of diurnal patterns via L2-orthogonal functional "principal components". The resulted principal component scores can be used. Here, FPCA is done by using the `fpca.face` function in the refund package. It is suggsted to take the log transformation to reduce the skewness of count data by setting `logtransform = TRUE`. 

Notice that, here, for simplicity and better interpretability, for each subject, we take the average across all valid days, therefore, we don't account for the within person correlation. To incorporate the within person correlation, one can choose to use multilevel FPCA by using the `denseFLMM` function in the denseFLMM package.
