Abstract
Regresi tersensor merupakan model yang digunakan untuk menggambarkan keadaan data sampel tersensor, yaitu bila variabel tak bebas untuk model rearesi terdapat data yang hilang atau tidak dapat terambil. Penaksiran parametemya • menggunakan metode maksimum likelihood, sedangkan untuk pengujian hipotesisnya digunakan uji rasio likelihood. Dengan menggunakan metode maksimum likelihood diperoleh koefisien regresi tersensor. Dengan menggunakan uji rasio likelihood yaitu membandingkan fungsi log likelihood tanpa variabel bebas dengan fungsi log likelihood dari seluruh variabel bebas dapat diketahui signifikan tidaknya parameter, sehingga dapat diperoleh signifikan tidaknya model. Cencored regressions is a model that used to expression a cencored sample that some observations on the dependent variable for rearessions model are missing or are not observable. The method of maximum likelihood are used to estimate the parameters and the likelihood ratio test are used to test the hipothesis. The coefficients of a cencored regressions will find with the maximum likelihood method. To test the significance of all of a subset of the coefficient by comparing the value of the likelihood function when all coefficients are set to zero, except the constant with the maksimum value of the likelihood function.
