BUBBLEPLOT Subcommand (META ES CONTINUOUS command)

The META ES BINARY command calls the meta-analysis procedure for binary outcomes when the pre-calculated effect size data are provided in the active data set. The optional BUBBLEPLOT subcommand invokes the bubble plot. The subcommand is not specified by default, which suppresses the bubble plot. When the subcommand is specified, it takes the following parameters and keywords to create the bubble plot.

PREDICTORS

The required keyword specifies the variables that are treated as continuous predictors on the x-axis. Multiple variables are allowed with each variable creating a separate bubble plot. Note that variable_list cannot contain string variables or variables already specified by /DATA ID and/or /DATA STUDY.

CENTER

The optional keyword controls the continuous predictor on the x-axis. FALSE is the default setting, which does not center the predictor. When TRUE is specified, the predictor is mean-centered.

PROPORTION

The optional keyword controls the bubbles. TRUE is the default setting, which draws bubbles proportional to the weights. When FALSE is specified, bubbles are drawn in the same size.

FITLINE

The optional keyword controls the fitted line. TRUE is the default setting, which adds the fitted regression line to the bubble plot. When FALSE is specified, the line is suppressed.

CI

The optional keyword controls the confidence interval bounds. TRUE is the default setting, which adds the confidence interval bounds to the bubble plot. When FALSE is specified, the confidence interval bounds are suppressed.

LABEL

The optional keyword specifies the variable upon which the labeled bubble plot is based. The variable can be followed by an additional keyword specified in parentheses. AUTO is the default setting, which automatically places the labels in the “optimal” place. UPPER, BOTTOM, RIGHT, and LEFT places the labels on the upper, bottom, right, and left, respectively.

YRANGE

The optional keyword specifies the y-axis plot range. When the keyword is specified, two numeric values must be specified and satisfy value2 > value1. When /DATA ESTYPE = RD, it must also satisfy value2 ≤ 1 and value1 ≥ −1. Note that the user-specified values apply to all bubble plots in the presence of multiple variables specified by PREDICTORS.

XRANGE

The optional keyword specifies the x-axis plot range. When the keyword is specified, two numeric values must be specified and satisfy value2 > value1. Note that the user-specified values apply to all bubble plots in the presence of multiple variables specified by PREDICTORS.
