The single-index model (SIM) is a simple asset pricing model to measure the interest rate on treasury bills): rmt is the return to the market portfolio in period t: α  

gerard.biau@upmc.fr. Abstract. Let (X,Y ) be a random pair taking values in Rp × R. In the so- called single-index model, one has Y = f⋆(θ⋆T X) + W, where f⋆ is. + R ……………….. (10), which establishes the linear relationship between security return and market return and is known as the Sharpe's Single Index Model. 6 May 2013 where xi's are subject-specific covariate vectors, β = (β1, …, βp)T, yi ∈ ℝ, η is an unknown function, ε1, …, εn are iid errors with mean zero and  Let (X,Y) be a random pair taking values in Rp × R. In the so-called single-index model, one has Y = f*(θ*TX)+W, where f* is an unknown univariate measurable

Single‐index models are popular regression models that are more flexible than linear models and still maintain more structure than purely nonparametric models. We consider the problem of estimating the regression parameters under a monotonicity constraint on the unknown link function. The semiparametric single index regression model is E(y j x) = g x0 (1) where g is an unknown link function. The semiparametric single index binary choice model is P (y = 1 j x) = E(y j x) = g x0 (2) where g is an unknown distribution function. We use g (rather than, say, F) to emphasize the connection with the regression model.

The single-index model (SIM) is a simple asset pricing model to measure both the risk and the return of a stock. The model has been developed by William Sharpe in 1963 and is commonly used in the finance industry. the single index model method, one of either “ichimura” (default) (Ichimura (1993)) or “kleinspady” (Klein and Spady (1993)). Defaults to ichimura. nmulti: integer number of times to restart the process of finding extrema of the cross-validation function from different (random) initial points. Defaults to min(5,ncol(xdat)). random.seed
