This function allows to estimate diachronic competition between two products, according to the Unbalanced Competition Regime Change Diachronic model, UCRCD, (Guseo and Mortarino, 2014).
UCRCD(sales1, sales2, c2, display=T, alpha=0.05,
delta=0.01, gamma=0.01, par="double",
m1 =BASS.standard(sales1,display = F)$Estimate[1,1],
m2 =BASS.standard(sales2,display = F)$Estimate[1,1],
p1c=BASS.standard(sales1,display = F)$Estimate[2,1],
q1c=BASS.standard(sales1,display = F)$Estimate[3,1],
p2c=BASS.standard(sales2,display = F)$Estimate[2,1],
q2c=BASS.standard(sales2,display = F)$Estimate[3,1])
Instantaneous sales of the first product
Instantaneous sales of the second product
Time at which the second product enters the market
T or F, to display the plot of the model or not, the default value is T
Desired significance level, the default value is 0.05
Preliminary estimates for parameter delta
Preliminary estimates for parameter gamma
Default value is par = ”double”, where delta is different from gamma. If par = "unique", delta is equal to gamma
Preliminary estimates of the first product's market potential under competition
Preliminary estimates of the second product's market potential
Preliminary estimates of the first product's innovation coefficient under competition
Preliminary estimates of the second product's innovation coefficient under competition
Preliminary estimates of the first product's imitation coefficient under competition
Preliminary estimates of the second product's imitation coefficient under competition
