Prepare Input Matrix from interest1981 Dataset

Source: R/data.R
input2.Rd

The input2 object is a matrix created from the interest1981 dataset for further analysis. The process involves extracting relevant columns, filtering rows, transforming values, and handling missing data.

Format

A numeric matrix with rows corresponding to filtered observations and columns representing transformed variables.

Details

The input2 matrix is derived from the interest1981 dataset through the following steps:

  1. Extract relevant columns: input <- as.matrix(interest1981[, 9:38])

  2. Filter rows with sufficient data: input <- input[rowSums(!is.na(input)) >= 5, ]

  3. Transform the matrix: input <- (100 - input) / 50

  4. Square the matrix to create input2: input2 <- input * input

  5. Handle missing values: input2[is.na(input)] <- (mean(input, na.rm = TRUE))^2

data(input2)
input <- as.matrix(interest1981[, 9:38])
} # }
