Due Date 07/11/2017

Initial requirements: 1. Remove NA:

• type:
  • 'none' - without changes
  • 'zero' - replace NA to 0,
  • 'linear' - using linear interpolation,
  • 'mean' - replace NA to mean of all time series data

2. Remove outliers :

• type:
  • 'none' - without changes,
  • 'normal' - replace outliers of data to quantile,
  • 'diff' - replace outliers of differences to quantile
• number - count of sigma for non outliers interval (from 3 to 7, default - 5)

3. Denoising :

• type :
  • 'none' - without changes,
  • 'gaussian',
  • 'sma' - arithmetic mean of the series over the past n observations
  • 'ema' - exponentially-weighted mean, giving more weight to recent observations.
• window_noise - kernel size
  • 'auto' - auto-detected
  • 'manual' - selection is possible
• window size (if manual) - from 3 to 25, default - 5

4. Aggregation : type and step slider are determined based on timeSliders.R function

@vsolskyy Please, apply following changes to Data Transformation page:

1. Outliers and Denoising: add option None to the InputSelection control
2. Remove NA values : set Zero option as Default
3. Remove NA values, Outliers, Denoising and Aggregation procedures have to be called in that order without excluding. If one or other operation should be skipped, type "None" should be set.
