metamean.test {bda} | R Documentation |
To test the equality of two means based on two sequences of sample means.
metamean.test(x,n,group,s,mu, sigma,years, alternative = c("two.sided", "less", "greater"), conf.level=0.95, sizable=FALSE,legend.pos=2)
x,n,s |
Vectors of sample means, sample sizes, and sample standard
deviations. |
mu, sigma |
The vectors of the mean and standard deviation values for the populations or much larger sample. |
years |
The years of the collected data. If missing, replace with a
sequence of integers starting with |
group |
A vector showing the group IDs. Must have two levels. |
alternative |
Type of test. |
conf.level |
Confidence level if the means. |
sizable |
A logical variable to control the size of the point symbols. |
legend.pos |
Position of the legend: 1=top right, 2=top left, 3=bottom left, 4=bottom right, 0=no legend. |
