Abstract
Recent progress in the quantitative analysis of Wolf-Rayet stars is reviewed, emphasising the role played by choice of spectral diagnostics, clumping and line-blanketing on derived stellar properties. The ionizing properties of WR stars are discussed, based on clumped, line-blanketed models for WN and WC stars. The role of metallicity and mass-loss is assessed, and the role of H II regions as probes of predicted Lyman continuum distributions. Suggestions are made for differences in observed properties of WCE and WO subtypes.
