In jentjr/manager: Tools for plotting and analyzing environmental data

Function to return either normal, lognormal, or non-parametric distribution

Description

Function to return either normal, lognormal, or non-parametric distribution

Usage

est_dist(
  df,
  alpha = 0.05,
  method = "sw",
  choices = c("norm", "lnorm"),
  combine_locations = FALSE,
  keep_data_object = FALSE
)

Arguments

df	groundwater data frame in tidy format
alpha	alpha
method	default is "sw"
choices	vector of distributions to check. Default is c("norm, "lnorm")
combine_locations	TRUE/FALSE to estimate distribution by individual location, or grouped together. Default is FALSE.
keep_data_object	Default is FALSE

Examples

data("gw_data")
wells <- c("MW-1", "MW-2", "MW-3", "MW-4")
params <- c("Sulfate, total",
            "Arsenic, dissolved",
           "Boron, dissolved")

gw_data <- gw_data %>%
filter(location_id %in% wells, param_name %in% params) %>%
percent_lt() %>%
filter(percent_lt <=15)

gw_data %>%
group_by(location_id, param_name, default_unit) %>%
est_dist(., alpha = 0.05, keep_data_object = FALSE)


gw_data %>%
group_by(param_name, default_unit) %>%
est_dist(., combine_locations = TRUE, keep_data_object = FALSE)
