Inverse Normal Calculation

Usage

iscaminvnorm(prob1, mean = 0, sd = 1, direction)

Arguments

prob1: probability to find normal quantile of.
mean: mean of normal distribution.
sd: standard deviation of normal distribution.
direction: direction for probability calculation: "above", "below", "outside", "between".

Value

a plot of the normal distribution with the quantile of the specified probability highlighted.

Examples

iscaminvnorm(0.05, direction = "below")

#> The observation with 0.05 probability below is -1.645 
iscaminvnorm(0.90, mean = 100, sd = 15, direction = "above")

#> The observation with 0.9 probability above is 80.78 
iscaminvnorm(0.10, direction = "outside")

#> There is 0.1 probability outside -1.645 and 1.645 
iscaminvnorm(0.95, direction = "between")

#> There is 0.95 probability between -1.96 and 1.96
