For a multiple regression analysis (that is, where the levels of the predictor variables are fixed rather than random), one can use the program Conf-Interval-R2-Reg which is available at Wuensch's SAS Programs Page. This program was adapted from one of those presented in Kline (2004). For SPSS scripts to do the same, download CI-R2-SPSS.zip .
For a multiple correlation analysis (that is, where the levels of the predictor variables are random rather than fixed), one can use Jim Steiger’s R2 program.
