Value

Return a dataset with three columns: patient identifier, caculated QRISK3 score, caculated QRISK3 score with only 1 digit

Usage

data(QRISK3_2017_test)

Format

An object of class data.frame with 48 rows and 27 columns.

Examples

data(QRISK3_2017_test)
str(QRISK3_2017_test)

Test data for QRISK3 2017 algorithm - 2019 data

Description

Data from QRISK3 original algorithm (C code) in 2019 <https://qrisk.org/three/src.php>. The aim is to compare whether this package calculates the same score as the original algorithm. "QRISK_C_algorithm_score" in dataset is the score calculated using original algorithm in 2019. It should give the same score as this package. This data was similar to QRISK3_2017_test except that several test values have been changed.

Usage

data(QRISK3_2019_test)

Format

An object of class data.frame with 49 rows and 27 columns.

Examples

data(QRISK3_2019_test)
