where Xt is the t-th 15-minute spot

where Xt is the t-th 15-minute spot JPY/USD exchange rate, Ot1 denotes the time t1 information set, and 2 Xt represents the conditional variance of the exchange rates in each 15-minute interval. The estimated conditional P-GARCH variance ^ 2 Xt is presented in Table 2. Figure 2 plots the three measures of exchange rate variances over 15-minute intervals. The patterns of the range and calculated variance are similar and the estimated conditional P-GARCH variance has comparatively larger fluctuations.

mana Xt t-th 15 menit spot JPY USD nilai tukar, PL 1 menunjukkan informasi waktu t 1 set, dan 2 Xt mewakili varians bersyarat tukar dalam interval 15 menit masing-masing. Perkiraan bersyarat P-GARCH varians ^ 2 Xt disajikan dalam tabel 2. Gambar 2 plot sukatan kurs varians selama 15 menit interval. Pola beragam dan dihitung varians serupa dan varians P-GARCH bersyarat diperkirakan telah fluktuasi yang relatif lebih besar.
