Description

A collection of functions to handle tasks commonly used in developing decision models.

Probabilities and Rates

ProbToRate converts a cumulative probability over a given time frame to a rate.

RateToProb converts a rate to a cumulative probability over a given time frame.

ProbToOdds converts a probability to an odds.

OddsToProb converts an odds to a probability.

Distributions

estBetaParam estimates parameters for a beta distribution given a mean and standard deviation using method of moments.

estGammaParam estimates parameters for a gamma distribution given a mean and standard deviation using method of moments.

estLogNormParam estimates parameters for a lognormal distribution given one of:

• mean and standard deviation, or

• mean and lower/upper bounds of a 95% confidence interval.

Other

GetDiscount returns an instantaneous discount rate for a vector of time points.

roundToMult returns a vector of values rounded to the nearest multiple specified by the user.

convertFilepath converts backslashes in a Windows filepath to a character string containng forward slashes.

lerp is a linear interpolation function that only uses two points on a curve. May be faster than the base R function for decision models.

Tools

fieller returns Fieller's confidence interval for a ratio of two vectors.

confintVector returns a confidence interval of a vector using a normal distribution.
