Finds sample means and variances for a matrix of observations when replicates are present
uniqueSummary(X,Y)
X |
matrix of inputs |
Y |
matrix of outputs corresponding to x |
uniqueSummary
calculates sample means and variances for each unique input. For input values with no replicates, the sample variance will be ‘NA’. This function is used by mlegp
to fit a GP to a collection of means observations at each design point.
A list with the following components:
reps |
the number of reps for each unique design point |
uniqueX |
the input matrix with duplicate inputs removed |
uniqueMeans |
sample means corresponding to each unique input |
uniqueVar |
sample variances corresponding to each unique input |
