weight_data: Weight data

In mladenjovanovic/bmbstats: Bootstrap Magnitude-Based Statistics

Description

Example data to demonstrate measurement error concept. Data consists of 20 athletes with their True Score (TS) bodyweight (kg) and five Observation Scores (OS) measured over 5 occasions using measuring scale with fixed bias, proportional bias, and random error. The mathematical notation is the following:

OS = Fixed\; Bias + (Proportional \; Bias\times TS) + ε

The following relationship between TS and OS is used in this data sample:

OS = 1 + (1.01 \times TS) + \mathcal{N}(0,\, 0.5)

Usage
