curvebox_data: Curve Boxplot Data

In fdasrvf: Elastic Functional Data Analysis

Curve Boxplot Data

Description

This function constructs the amplitude boxplot.

Usage

curvebox_data(align_median, alpha = 0.05, ka = 1)

Arguments

align_median	object from curve_karcher_mean() of aligned curves using the median
alpha	quantile value (default=.05, i.e., 95%)
ka	scalar for outlier cutoff (default=1)

Value

Returns an curvebox object containing:

• median_y: median curve

• Q1: First quartile

• Q3: Second quartile

• Q1a: First quantile based on alpha

• Q3a: Second quantile based on alpha

• minn: minimum extreme curve

• maxx: maximum extreme curve

• outlier_index: indexes of outlier curves

• fmedian: median curve
