speed_accel_observations: Speed-Acceleration Model Observations

In aaronzpearson/midsprint: {midsprint} makes building in-game player profiles easy

Description

This function returns the observations that were utilized to build an athlete's speed-acceleration profile. As suggested by Morin and colleagues, the top two acceleration values per speed bin, cut every 0.2 m/s equal to, or above 3 m/s, are maintained. A linear model is then built and points are removed until an r squared value of 0.95 or greater is reached.

You can also call upon accel_speed_observations for the same output.

WARNING: This function returns the values that make up the final linear model. No intermediary values, the initially binned observations, are returned.
