Generating simulations in r
WebJun 28, 2015 · Regardless, applying min (or, more generally, pmin) is the way to simulate it in R. (An example of right censoring in a non-survival study is the analysis of bacterial colonies in wastewater. It is done by manually counting those visible on a microscope slide. With heavy contamination, the result is given as "too numerous to count.") – whuber ♦ WebMohamed R. Abonazel: A Monte Carlo Simulation Study using R Step 4: Generate the fixed values of the independent variables matrix X under A2 and A3.
