how do you maximize variance why is variance higher in a set b lamp or higher in dp which describes how you can maximize the variance and maximize the means? theorem how to minimize variance how to find the optimal combination of variance and mean calculate the sum of variance and mean of the lifetime of the lamp in an optimisation what is meant by the variance of the lamps lifetime how to calculate minimizing variance on a lamp how to maximize variance and increase mean which method can minimizing mean be used? calculate variance while maximizing mean what is minimizing variance for variance why do you need to optimize variance and mean how do you minimize variance how to find optimal combination of variance and mean which method is used maximizing means and minimizing variance to optimize the life span of each light cycle? why is variance important to optimisation what is meant by the mean of variance of the lifetime of a lamp? how to maximize variance and mean what is the variance of a lamp
