util_normal_param_estimate {TidyDensity}

Estimate Normal Gaussian Parameters

Description

The function will return a list output by default, and if the parameter .auto_gen_empirical is set to TRUE then the empirical data given to the parameter .x will be run through the tidy_empirical() function and combined with the estimated normal data.

Three different methods of shape parameters are supplied:

• MLE/MME

• MVUE

Usage

util_normal_param_estimate(.x, .auto_gen_empirical = TRUE)

Arguments

.x

The vector of data to be passed to the function.

.auto_gen_empirical

This is a boolean value of TRUE/FALSE with default set to TRUE. This will automatically create the tidy_empirical() output for the .x parameter and use the tidy_combine_distributions(). The user can then plot out the data using ⁠$combined_data_tbl⁠ from the function output.

Details

This function will attempt to estimate the normal gaussian mean and standard deviation parameters given some vector of values.

Value

A tibble/list
