The CAPABILITY Procedure

Overview

You can specify several new options to enhance histograms and comparative histograms produced by the CAPABILITY procedure. In both the COMPHISTOGRAM and HISTOGRAM statements you can specify:

the BARLABEL= option to display labels over histogram bars
the CLIPSPEC= option to clip histogram bars at the specification limits
the ENDPOINTS= option to label histogram endpoints instead of midpoints

In the COMPHISTOGRAM statement you can specify the CTEXTSIDE= and CTEXTTOP= options to control the colors of row and column labels. In the HISTOGRAM statement you can use the NMIDPOINTS= or NENDPOINTS= option to specify the number of histogram interval midpoints or endpoints.

The table produced by the SPECIALINDICES option in the PROC CAPABILITY statement now contains additional specialized process capability indices. The new indices are S_jkp, C_pp, C_pp^'', C_pg, C_pq, C_p^W, C_pk^W, C_pm^W, C_pc, C_p(u,v), and C_p(v).
