Stata Programs: Sample Size for Cost-Effectiveness Analysis

  • "Immediate form" programs to estimate sample size and power when 1) the standard deviation of costs and the standard deviation of effects are common for two treatment groups (cess1i and cepow1i) 2) the sample size is common but the standard deviation of costs and the standard deviation of effects differ between two treatment groups (cess2i and cepow2i); and 3) the sample size differs but the standard deviation of costs and the standard deviation of effects are common for two treatment groups (cedssi and cedpowi). Also included is a log file that demonstrates use of the 6 programs. (last updated, 03/29/10)
