ni alamat emailna ---->>> heungsun.hwang@mcgill.ca
ada beberapa pertanyaan yg udah tak tanyain. aq share aja isi email na toh buat pembelajaran (muup bhs inggris q berantakan)
- Why in process parameter estimasi employ vec (x) ?? and why GSCA not need a distribution assumpsi??
- How is the procedure for fixed V and W with given value in the First step of ALS algorithm. is it randomly or other way ? how is the way of given value of fixed V and W?
- had the regularized GSCA been applied in software GeSCA ??
- If we want estimate W(2) (GSCA second orde) , what is we must estimate W(1) previously ??
jawaban dari Mr Hwang
- We need the vec operator to estimate only free parameters (except any fixed ones such as zeros) in W, C, and B. GSCA estimates parameters based on least squares. This is why it does not rely on the normality assumption. In addition, GSCA uses the bootstrap method to estimate the standard errors of parameter estimates without recourse to the assumption.
Heungsun - Yes, they are given randomly in the software.
Best wishes,
Heungsun - Unfortunately, regularized GSCA is not yet implemented into the software.
Heungsun - Yes, you need to estimate W(1) and W(2) sequentially.Heungsunini kata-kata na asli. ga ada yang tak kurangi. kecuali yang bagian beliau nyapa n kadang minta maaf karena ga bisa bales cepet gara2 sibuk ngajar .ada beberapa pertanyaan yang pernah tak tanyain. tp ternyata udah tercantum di makalah jadina ga ta cantumin. tips na biar pertanyaan qt efektif tuuch.. nanyana satu2 aja. jgn bareng2. pengalaman pertama nanya tu pertanyaane banyaaak.. eh yg dibales pertanyaan terakhir duang.asli.. kaget banget pas beliau welcome gitu. padahal biasana lo qt email profesor dalam negeri di baca aja kagak. boro-boro dibales. mungkin Mr Heunsung ngerasa tulisanna di hargai orang laen. but whatever motif beliau mbales email. ya meskipun kata-katana singkat n ga mesti dibales cpt tapi setidakna beliau merespon pertanyaan qt. so Thanks A lot to Mr Heunsung Hwang.
