phe_mean: Calculate Means using phe_mean

In PHEindicatormethods: Common Public Health Statistics and their Confidence Intervals

Calculate Means using phe_mean

Description

Calculates means with confidence limits using Student's t-distribution method.

Usage

phe_mean(data, x, type = "full", confidence = 0.95)

Arguments

data	a data.frame containing the data to calculate means for, pre-grouped if multiple means required; unquoted string; no default
x	field name from data containing the values to calculate the means for; unquoted string; no default
type	defines the data and metadata columns to be included in output; can be "value", "lower", "upper", "standard" (for all data) or "full" (for all data and metadata); quoted string; default = "full"
confidence	the required level of confidence expressed as a number between 0.9 and 1 or a number between 90 and 100 or can be a vector of 0.95 and 0.998, for example, to output both 95 percent and 99.8 percent percent CIs; numeric; default 0.95

Value

When type = "full", returns a data.frame of value_sum, value_count, stdev, value, lowercl, uppercl, confidence, statistic and method for each grouping set

Examples

library(dplyr)
df <- data.frame(values = c(30,40,50,60))

## default execution
phe_mean(df, values)

## calculate 95% and 99.8% CIs in single execution
phe_mean(df, values, confidence = c(0.95, 0.998))

## calculate multiple means in a single execution

df2 <- data.frame(area = rep(c("Area1", "Area2"),each=3),
                  values = c(20,30,40,200,300,400)) %>%
                  group_by(area)
phe_mean(df2,values)
phe_mean(df2,values,type="standard", confidence=0.998)
