These data (hsb2) were collected on 200 high schools students and are scores on various tests, including science, math, reading and social studies (socst). The interpreting multiple regression output spss variable female is a dichotomous variable coded 1 if the student was female and 0 how to write a regression equation from spss output if male. In the syntax below, the get file command is used to load the data into SPSS. In quotes, you need how to report regression results spss to specify where the data file is located on your computer. In the regression command, the statistics subcommand must come before the dependent subcommand. You list the independent variables after the equals sign on the method spss output interpretation subcommand. The statistics subcommand is not needed to run the regression, but on it we can specify options that we would like to have included in the output. Please note that SPSS sometimes includes footnotes as part of the output. We have left those intact and have started ours with the next letter of the alphabet. get file "c:\hsb2.sav". regression /statistics coeff outs r anova ci /dependent science /method = enter math female socst

read. Variables in the model c. Model - SPSS allows you to specify multiple models in a single regression command. This tells you the number of the model being reported. d. Variables Entered - SPSS allows you to enter variables into a regression in blocks, and it allows stepwise regression. Hence, you need to know which variables were entered into the current regression. If you did not block your independent variables or use stepwise regression, this column should list all of the independent variables that you specified. e. Variables Removed - This column listed the variables that were removed from the current regression. Usually, this column will be empty unless you did a stepwise regression. f. Method - This column tells you the method that SPSS used to run the regression. "Enter" means that each independent variable was entered in usual fashion. If you did a stepwise regression, the entry in this column would tell you that. Overall Model Fit b. Model - SPSS allows you to specify multiple models in a single regression command. This tells you the number of the model being reported. c. R - R is the square root of R-Squared and is the correlation between the observed and predicted values of dependent variable. d. R-Square - This is the proportion of variance i

reading and social studies (socst). The variable female is a dichotomous variable coded linear regression analysis spss 1 if the student was female and 0 if male. In the syntax below, the get file command is used interpreting beta coefficients in multiple regression to load the data into SPSS. In quotes, you need to specify where the data file is located on your computer. Remember that you need to use the .sav extension and that you http://www.ats.ucla.edu/stat/spss/output/reg_spss.htm need to end the command with a period. In the regression command, the statistics subcommand must come before the dependent subcommand. You can shorten dependent to dep. You list the independent variables after the equals sign on the method subcommand. The statistics subcommand is not needed to run the regression, but on it we can specify options that we would like to have included in the http://www.ats.ucla.edu/stat/spss/output/reg_spss_long.htm output. Here, we have specified ci, which is short for confidence intervals. These are very useful for interpreting the output, as we will see. There are four tables given in the output. SPSS has provided some superscripts (a, b, etc.) to assist you in understanding the output. Please note that SPSS sometimes includes footnotes as part of the output. We have left those intact and have started ours with the next letter of the alphabet. get file "c:\hsb2.sav". regression /statistics coeff outs r anova ci /dependent science /method = enter math female socst read.

It contains the names of the items in the equation and labels each row of output. The Unstandardized coefficients (B) are the regression coefficients. The regression equation is STRENGTH = -13.971 + 3.016 LBM regression analysis spss The predicted muscle strength of someone with 40 kg of lean body mass is -13.971 + 3.016 (40) = 106.669 For cross-sectional data like these, the regression coefficient for the predictor is the difference in response per unit difference in the predictor. For longitudinal data, the regression coefficient is the change in response per unit change in the predictor. Here, strength differs 3.016 units for every unit difference in lean body mass. The distinction between cross-sectional and longitudinal data is still important. These strength data are cross-sectional so differences in LBM and strength refer to differences between people. If we wanted to describe how an individual's muscle strength changes with lean body mass, we would have to measure strength and lean body mass as they change within people. The Standard Errors are the standard errors of the regression coefficients. They can be used for hypothesis testing and constructing confidence intervals. For example, the standard error of the STRENGTH coefficient is 0.219. A 95% confidence interval for the regression coe
