_D_e_s_c_r_i_p_t_i_o_n_:

     This data set is from a simulation of a servo system
     involving a servo amplifier, a motor, a lead screw/nut,
     and a sliding carriage of some sort. It may have been
     on of the translational axes of a robot on the 9th
     floor of the AI lab. In any case, the output value is
     almost certainly a rise time, or the time required for
     the system to respond to a step change in a position
     set point. The variables that describe the data set and
     their values are the following:

     [,1]      Motor     A,B,C,D,E
      [,2]     Screw     A,B,C,D,E
      [,3]     Pgain     3,4,5,6
      [,4]     Vgain     1,2,3,4,5
      [,5]     Class     0.13 to 7.10
