One parameter model for error in instantaneous centre of rotation measurements.
Many statistical distributions have a single parameter which describes its spread. In the kinematic study of the instantaneous centre of rotation, error in data cause a non-symmetrical distribution for the centre. As an aid in describing its spread, the analytical form of the probability density function was reduced to a single-parameter model. This results in a convenient way of analysing experimental data through the use of an 'ICR Error Chart'.
