This paper addresses variable selection problems in sparse logistic regression model with errors-in-covariates. We propose a corrected score Lasso method, which combines the weighted score Lasso approach with a projected gradient descent algorithm, to handle the challenges posed by measurement errors. The weighted score Lasso introduces a correction-amenable score function, enabling direct extension to measurement error scenarios through subsequent score correction. Our method bridges the gap between rigorous measurement error correction and practical high-dimensional implementation, establishing a framework extensible to other generalized linear models with exponential family structure. Numerical studies demonstrate the superior performance of the corrected score Lasso in error correction scenarios, highlighting its potential as a robust tool for high-dimensional data analysis with measurement error.
