shorts 1.1.2

• Added get_air_resistance function to estimate air resistance in newtons
• Added predict_air_resistance_at_time and predict_air_resistance_at_time functions
• Added predict_force_at_time and predict_force_at_distance functions
• Added predict_power_at_time and predict_power_at_distance functions
• Now power calculations in predict_relative_power_at_distance and predict_relative_power_at_time use air resistance to do the calculations. The default bodymass is 75kg. To replicate earlier function behavior, use predict_velocity_at_ multiplied by predict_acceleration_at_ to get relative power without air resistance
• Function predict_kinematics now uses aforementioned changes in predict_relative_power_ functions, and added force and air resistance in the output
• Functions find_max_power_distance and find_power_critical_distance now uses aforementioned changes and returns absolute power, rather than relative, and air resistance is used in the power calculations
• Added find_max_power_time, find_velocity_critical_time, find_acceleration_critical_time, and find_power_critical_time functions
• Added model_using_radar_with_time_correction where time_correction parameter is estimated
• Added mixed_model_using_radar_with_time_correction where time_correction parameter is estimated

shorts 1.1.1

• Added James Vescovi contributed dataset (data("vescovi")). For more info see ?vescovi

shorts 1.1.0

• Used constructor functions for all modeling functions
• Added modular short_model_fit function with three extra estimators: MAE, MAPE, and MaxAbsErr. This function is hidden from the user, but allows easier extension and modularity as well avoidance of code repetition
• Added time_correction and distance_correction to all model parameters output to align them
• Added S3 predict_kinematics function that predicts 0-6s distance (100Hz), velocity, acceleration, and relative power
• Added S3 print, coef, summary, predict, and residuals methods
• Added LOOCV option to modeling functions which provided cross-validated predictions and estimated model parameters
• Added random parameter to mixed_ family of functions to allow higher flexibility in model definitions, but removed corrections_as_random_effects parameter. The default behavious is to use all parameters as random effects.
• Added ... to model_using_radar and mixed_model_using_radar to be forwarded to nlme::nlme
• Expanded the Readme.md file
• Expanded the sprint-corrections vignette by adding a short simulation study

shorts 1.0.1

• Corrected the error in vignette that showed on Solaris system. Increased the random noise to allow nls to fit

shorts 1.0.0

• Renamed time_delay to time_correction in shorts::model_using_instant_velocity and shorts::mixed_model_using_instant_velocity functions to be more consistent across functions. Also, this correction is added to time, so use negative numbers instead
• time_correction in shorts::mixed_model_using_instant_velocity and shorts::mixed_model_using_split_times is now numeric vector, not column name
• Implemented time_correction in shorts::model_using_split_times and shorts::mixed_model_using_split_times
• Implemented time_correction in shorts:predict_ family of functions
• Implemented distance_correction in shorts:predict_ family of functions
• Implemented estimation of time_correction in shorts::model_using_split_times_with_time_correction and shorts::mixed_model_using_split_times_with_time_correction
• Implemented estimation of distance_correction in shorts::model_using_split_times_with_corrections and shorts::mixed_model_using_split_times_with_corrections
• Fixed error in calculating PMAX in shorts::mixed_model_ functions
• Removed maxAbsErr from model_fit element
• Wrote “sprint-corrections” vignette explaining the idea behind sprint time and distance corrections
• Implemented find_ family of functions for finding max power and critical distance when velocity or acceleration reaches certain threshold
• Implemented ... to all modeling functions so that extra parameters can be forwarded to the optimization engine
• Data split_times recreated using distance shift behind the first timing gate. Needed to demo mixed models with corrections
• Renamed _model_using_instant_velocity to _model_using_radar
• Renamed _model_using_split_times_ to _model_using_splits_

shorts 0.0.1
