calculate_stats_gamma {simBKMRdata} | R Documentation |
Calculate summary statistics and gamma parameters for each group
Description
This function computes the sample size, gamma distribution parameters (shape and rate), and Spearman correlation matrix for each group, based on the grouping column.
Usage
calculate_stats_gamma(data_df, group_col, using = c("MoM", "gMLE"))
Arguments
data_df |
A data frame containing the data to be processed. |
group_col |
A character string specifying the name of the column to group by. |
using |
which method will be used to estimate the multivariate Gamma
shape and rate parameters. Defaults to |
Value
A list of lists, where each inner list contains:
sample size (n)
sample mean vector (mean)
gamma distribution parameters (shape, rate)
Spearman correlation matrix (cor)
Examples
myData <- data.frame(
GENDER = c('Male', 'Female', 'Male', 'Female', 'Male', 'Female'),
VALUE1 = c(1.2, 2.3, 1.5, 2.7, 1.35, 2.5),
VALUE2 = c(3.4, 4.5, 3.8, 4.2, 3.6, 4.35)
)
calculate_stats_gamma(myData, "GENDER")
