Tempo tempo tempo my nemesis. It hurts, it’s tough going but damn it, it’s beneficial. My issue is maintaining the pace because I always end up running too fast. Eventually I will get there but it’s not a friendly journey. #tempo #tempohell #intervals #sprint #intervalsprints #speed #speedwork #ultratraining #ultrarunning https://www.instagram.com/p/CiNs-qIo81x/?igshid=NGJjMDIxMWI=

Beginning exercise has been known for some time to help those with depression in reducing anxiety and improving mood. This is the first study showing the effect of stopping exercise. . . . #hiitworkout #personaltrainer #personaltraining #liverpool #merseyside #intervalsprints #prescot #huyton #pt #onetoonesessions #grouptraining #weightloss #weights #liftheavy #bodyfatreduction #fatburners #dm #tbt #crossfitathlete #crossfitosasco #crossfitfriends #crossfitforlife #crossfitwod #crossfitmen #messageforinfo #crossfitlife #crossfitbox #dietplans #crossfitlifestyle #crossfitcommunity https://www.instagram.com/p/BnlGmDen54T/?utm_source=ig_tumblr_share&igshid=my8jfu4qatgc

Making progress is about stepping up and challenging yourself. Decided today was a good day to bump up my sprints -> because if it doesn’t challenge you, it doesn’t change you, right?? #HIIT #sprints #intervals #intervalsprints #elliptical #ellipticalworkout #carbcycling #lowcarbday (at Club Siena DB)

Assignment 4

#First, change the dependent variable, price, to binary:

kc['price_r'] = kc['price'] for i in range(0,len(kc['price'])):       if kc['price'][i] > median:              kc['price_r'][i]=1       else:    kc['price_r'][i]=0

#Then, performa logistic regression with two variables: living room area and the parking lot area:

lreg2=smf.logit(formula = 'price_r ~ sqft_living_c + sqft_lot_c',data=kc).fit()print(lreg2.summary())

The result shows the parking lot p value is high, indicating the confidence is low for this variable.

#odd ratios with 95% confidence 

intervalsprint("odds ratios") params = lreg2.params conf = lreg2.conf_int() conf['OR']=params conf.columns = ['lower CI','upper CI','OR'] print(np.exp(conf))

From the odd ratios, it can’t tell which variables have a better correlation with the binary price variable.

C3W4 Logistic Regression

My hypothesis is to find out if there is a relationship between life expectancy and urban rate. Life expectancy is the response variable, while urban rate is the explanatory variable. Since the gapminder data set variables are all quantitative, I needed to create a new data frame for the variables and bin each into 2 categories. The 2 categories are based on each variable's mean value. For each variable, 1 is >= the variable;s mean while all else is 0.

The initial regression model shows there is a statistical relationship between life expectancy and urban rate (p=1.632e-11, OR=12.10, 95% CI=26.98). Potential confounding factors include HIV Rate, alcohol consumption, and income per person. 

It was found that incomerate has no statistical relationship in this model based on the p-value being 0.998. HIV Rate has a significant association with life expectancy (p=1.563e-10), but HIV has a lower OR (0.03). So HIV does have a significant relationship with life expectancy, but in an urban area the odds are low it will affect life expectancy. Alcohol consumption has a 3 times higher affect on life expectancy (OR=3.18, p=0.021, 95% CI=8.52) in urban areas even though it is less statistically significant than HIV Rate.

So the model output shows that life expectancy has significant statistical associations with urban rate and the confounding variables of HIV rate and alcohol consumption.

Kicking off a new week with another round of 10 interval swim sprints. I like interval workouts because they’re tough but doable AND they crank up my fat burner for the rest of the day! 🔥 I also love that there are so many ways to do interval workouts so you can make the workouts your own. #noexcuses #intervalsprints #swimming #swimsprints #fastedcardio #lowcarbworkout #carbcycling #hongkong #discoverybay #clubsiena
