.summary_cts_by_fu {eq5dsuite}

Wrapper to summarise a continuous variable by follow-up (FU)

Description

This function summarizes a continuous variable for each follow-up (FU) and calculates various statistics such as mean, standard deviation, median, mode, kurtosis, skewness, minimum, maximum, range, and number of observations. It also reports the total sample size and the number (and proportion) of missing values for each FU. The input 'df' must contain an ordered FU variable and the continuous variable of interest. The name of the continuous variable must be specified using 'name_v'. The wrapper is used in Table 3.1 (for VAS) or Table 4.2 (for EQ-5D utility)

Usage

.summary_cts_by_fu(df, name_v)

Arguments

df

A data frame containing the FU and continuous variable of interest. The dataset must contain an ordered 'fu' variable.

name_v

A character string with the name of the continuous variable in 'df' to be summarised.

Value

Data frame with one row for each statistic and one column for each FU.

Examples

df <- data.frame(fu = c(1,1,2,2,3,3), 
                 vas = c(7,8,9,NA,7,6))
.summary_cts_by_fu(df, name_v = "vas")
