ldmult {mixtools} | R Documentation |
Return the logarithm of the multinomial density function.
ldmult(y, theta)
y |
A vector of multinomial counts. |
theta |
A vector of multinomial probabilities. May have same number of
components as or one fewer component than y . In the latter case,
an extra component is appended so that theta sums to one. |
This function is called by multmixEM
.
ldmult
returns the logarithm of the multinomial density
with parameter theta
, evaluated at y
.
y<-c(2, 2, 10) theta<-c(.2, .3, .5) ldmult(y, theta)
